Checked the way a browser does it rather than the way curl does, and curl had given a false green: Gitea sends `Content-Security-Policy: default-src 'none'; style-src 'unsafe-inline'; sandbox` with every /raw/ response. That is deliberate - it is what makes serving raw HTML and SVG safe - but it also blocks the media load when a browser navigates straight to a video, so the tab stays blank with no error. The same URL plays fine as a subresource, which is exactly why the file's page in Gitea shows a player: that page embeds <video controls src=".../raw/branch/main/...mp4">. So the declaration's link is the /src/ page URL, and /raw/ is documented as the curl-and-download URL instead. Everything verified about both URLs is written down in step 5 - including the two ways to get a player with no Gitea chrome around it, if that is ever wanted: an unlisted YouTube upload, or dropping the header for this one path on the Gitea host's Caddy proxy, which must stay scoped to store-assets/ precisely because that header is what protects raw HTML and SVG. The file itself was never the problem: 200, video/mp4, Content-Disposition: inline, bytes sha256-identical to the recording, and Range: bytes=0-99 -> 206 with the matching Content-Range.

Google Play release checklist
Work top to bottom. Items marked [code] are already handled in this repository; the rest are things you must do in the Play Console / with your own accounts.
1. Identity and signing
- Final application id chosen:
de.softwareapp_hb.fotodup.finder(applicationIdinapp/build.gradle.kts). It can never be changed after the first release, so treat it as locked.namespaceand the Kotlin package of the same name are aligned with it; debug builds append.debug. - Generate an upload keystore (keep it safe; if you lose it you cannot
publish updates) — [code] done:
fotodup-upload.jksin the project root (git-ignored,alias upload),CN=Hadrian Burkhardt, L=Potsdam, C=DE. - Copy
keystore.properties.exampletokeystore.propertiesand fill it in. [code] done — the file is in place, and the Gradle build picks it up automatically and signs release builds; without it the release APK stays unsigned. - Enable Play App Signing in the Play Console and upload the certificate of
your upload key:
bash keytool -exportcert -alias upload -keystore fotodup-upload.jks -rfc > upload_cert.pemUpload key fingerprint (SHA-256), to confirm the right key was registered:AA:8C:3D:6C:D0:55:46:50:48:ED:04:3E:AF:34:2B:66:B4:13:87:C9:E0:DA:29:70:5A:0D:18:47:08:1A:4C:7A. Enrolment happens with the first upload: Google then holds the app signing key and this one only signs uploads. - Store the keystore + passwords in a password manager / secure vault. Back it up.
2. Versioning
- Set
versionName(user-visible) [code] —1.0.1inapp/build.gradle.kts. versionCode[code] — currently 2. It is the counter Play orders uploads by, so the first upload will be 2 and every later upload must be higher.
3. Build the release artefacts
./gradlew :app:bundleRelease # -> app/build/outputs/bundle/release/app-release.aab
./gradlew :app:assembleRelease # -> APK for local testing
- [code] verified 2026-10-13:
bundleReleaseandassembleReleaseboth succeed.app/build/outputs/bundle/release/app-release.aabis 2,944,100 bytes (sha256 f8e6a29a0daf60d025409e19be878c3e8f1359a06b3f9fca300bb4aec9ebb726) and is signed with the upload key. The release APK reportsversionCode=2 versionName=1.0.1 targetSdk=36and exactly the permission set listed in step 5 — noINTERNET, so "nothing leaves the device" holds in the shipped artefact, not just in the source manifest. - Upload the
.aab(not the APK) to the Play Console. ⚠️ Expect a native-debug-symbols warning here, and ignore it. Play scans the bundle, findsbase/lib/<abi>/libandroidx.graphics.path.so, and reports "This App Bundle contains native code, and you've not uploaded debug symbols". It is a recommendation, not an error: it does not block the upload, review or rollout. - That one library (4 ABIs, ~37 KB total) is not this project's code — it arrives transitively throughandroidx.compose.ui:ui-graphics→androidx.graphics:graphics-path:1.0.1. The project has nondk/externalNativeBuild/jniLibsconfig and no native sources at all. - There is nothing to upload: the publishedgraphics-path-1.0.1.aarships stripped libs (symtab=0, no.debug_*sections, no symbol entries anywhere in the AAR), and the commonly-suggested fix does not apply — withndk.debugSymbolLevel = "FULL"the build succeeds but produces noapp/build/outputs/native-debug-symbols/output and adds nothing to the bundle, because AGP only packages symbols for native code it builds itself. - Excluding the lib (packaging { jniLibs { excludes += "**/libandroidx.graphics.path.so" } }) would silence the warning but risksUnsatisfiedLinkErrorinside Compose's path handling, for a 37 KB saving. Not worth it. - What it actually costs: symbolication of frames inside that Compose helper. Kotlin/Java crashes are unaffected — the R8 mapping rides inside the bundle (BUNDLE-METADATA/com.android.tools.build.obfuscation/proguard.map), so Play deobfuscates them automatically. - Keep
app/build/outputs/mapping/release/mapping.txtfor every release so you can de-obfuscate crash reports (upload it under Release > App bundle explorer).
4. Store listing
Ready-to-paste copy and the generated graphics live in docs/STORE_LISTING.md (milestone M10). Everything below is a Console action except the items marked [code].
- ⚠️ App pricing — do this before the first upload; it is the one irreversible decision.
Play, Set up your app's prices: "You can change your app from paid to free. Once your app has
been offered for free, the app can't be changed to paid. If you want to charge for the app, you
need to create a new app with a new package name and set a price." This release has not been
uploaded yet (
versionCode2 is the first), so a paid app is still possible; after the first upload to any track it is not. In the Console: 1. Set up a payments profile with your tax rates (Play asks the first time you set a price). 2. Products > App pricing → "Your app is" → Make your app paid, and enter the base price €2.99 (one-time). Leave "Default price includes tax" off unless €2.99 is meant to be the final gross price in the EU — off, a German buyer pays €3.56. 3. Check the local prices Play derives for each country — a country with no price is a country where the app is unavailable. 4. [ ] Launch sale: 50% off (€1.49) for 14 days. A sale can only be created after the app is published (App pricing > Sales > Create sale), it can be live for 1–14 days at most, and 30 days must pass between one sale ending and the next starting — so this is a single deadline-driven window, not a permanently lower launch price. Percentage discounts must be between 10% and 100%. The original price is struck through everywhere except in 12 EU member states and the UK (Germany does show it). 5. [ ] Test the paid listing end to end: install your own copy through a promo code rather than a real purchase. A giveaway code is the only trial mechanism a paid app has, and it doubles as the check that a buyer really does receive a working app. [code] nothing to build: no Billing dependency, nocom.android.vending.BILLINGin the merged manifest. Rationale, the fee arithmetic and the sale rules: STORE_LISTING › App pricing. - App name (≤ 30 chars): "Foto Dup Finder" (15 chars).
- Short description (≤ 80 chars) — two options are drafted and length-checked in STORE_LISTING.md (69 and 65 chars). Neither says "free": the app is paid, so the claim would be false, and Play's metadata policy keeps price and promotional wording out of the title, icon and developer name.
- Full description (≤ 4000 chars) — drafted and length-checked in STORE_LISTING.md (2 426 chars, so there is room to grow). The one price line ("Pay once, then own it…") sits in the body for the same policy reason.
- App icon 512×512 PNG [code] —
tools/make-store-assets.shrenders it from the same vectors as the adaptive icon inres/drawable/ic_launcher_*. - Feature graphic 1024×500 PNG [code] — same script.
- Phone screenshots (at least 2, up to 8) [code] — four are captured and normalised to
1080×2160 in
store-assets/screenshots/phone/(committed): empty state, scanning (5353 / 5385), results (17 duplicate groups, 54 of 5385 photos, 83.5 MB reclaimable) and the Options menu. They were shot after a real permission grant and over the generated demo library (tools/make-demo-photos.py), so neither the "Photo access needed" banner nor a personal photo is in frame; the demo library is deleted from the test device again once the captures are done. Upload the four, then drag 03-results to first place — the results screen is the one that sells, and the empty state is the weakest opener. ⚠️ Play rejects a screenshot whose longer side is more than 2× its shorter side, so a 1080×2400 phone capture has to be cropped to 1080×2160;tools/make-store-screenshots.shdoes exactly that (status and navigation bars only). - 7-inch tablet screenshots [code] — captured on a
Nexus 7 2013AOSP Android 12 AVD (1200×1920 portrait,sw600dp) and normalised tostore-assets/screenshots/tablet-7in/(committed) withFORM_FACTOR=tablet-7in ./tools/make-store-screenshots.sh: the same four screens as the phone set, over the same generated demo library — empty state, scanning (“Looking for visually similar photos…” 20 / 22), results (2 duplicate groups, 16 of 22 photos, 43.7 MB reclaimable, scanned in 39.7 s) and the Options menu (✓ on Balanced). Play asks for at least 4 screenshots on tablets, so four is the floor, not the target. 📋 A tablet frame is already inside Play's 2:1 cap, so this form factor deliberately crops 0 px of system chrome; the tablet captures are the raw screencaps, flattened to 24-bit. - 10-inch tablet screenshots [code] — same run on a
medium_tabletAOSP Android 12 AVD (1600×2560 portrait,sw800dp), normalised intostore-assets/screenshots/tablet-10in/withFORM_FACTOR=tablet-10in: scanning at 20 / 22 and the same 2 groups · 16 of 22 photos · 43.7 MB reclaimable results screen, scanned in 53.1 s. ⚠️ Both AVDs ran in pure software emulation, because this machine exposes no/dev/kvm(-accel off -no-window -gpu swiftshader_indirect): ≈3 min to boot and 1–12 s per screenshot.hide_error_dialogswas turned on and animations off, because under software emulation SystemUI raises an ANR dialog that would otherwise sit in frame. Full recipe: STORE_LISTING › Screenshots › 7-inch and 10-inch tablets. - Category: Tools (or Photography — pick it before the tags, because it shapes the Suggested tags list). Tags: max 5, from Play's own list, not typed freely — and only two are honest for this app: Photography, plus optionally Privacy & security. Play's taxonomy contains no duplicate/cleanup tag at all, so do not pad the field with Photo editor just to fill it; the reasoning is in STORE_LISTING › Category and tags.
5. Policy and compliance
-
Host PRIVACY.md at a public URL and paste that URL into the Play Console. This is mandatory because the app accesses photos. The contact address in it is final (
softwareapp.hb@gmail.com), so the file publishes as-is. Hosting half done (2026-10-14): the working copy is published to the Gitea instance asfishfacegit/foto-duplicate-finder(origin=ssh://git@gitea-container.incus:2222/fishfacegit/foto-duplicate-finder.git), so the policy now has a public, login-free URL: - rendered HTML (use this one in the Console):https://gitea.softwareapp-hb.de/fishfacegit/foto-duplicate-finder/src/branch/main/PRIVACY.md- rawtext/plainfallback:https://gitea.softwareapp-hb.de/fishfacegit/foto-duplicate-finder/raw/branch/main/PRIVACY.mdWhat is left is the Console paste: open the URL in a private window to prove it needs no login, then put it in **App content › Privacy policy**. A dedicated HTML page (the landing page would do) reads better than a file view inside the repo; any static host works the same way, the requirement is only that the URL is public, stable and readable without an account. > **Note on Play's automatic translation:** it translates the *store listing*, not > the hosted policy. If you want the policy in another language, host a translated > copy yourself and link it from the listing. -
Complete the Data safety form:
- Does your app collect or share any required user data types? → No.
- Data types accessed: Photos — processed on-device only, not collected.
- Is all user data encrypted in transit? → N/A (no transmission).
- Do you provide a way for users to request data deletion? → Uninstalling removes all app data.
- The paid model changes none of the above: the purchase happens in the Play Store app, not in this one. Play's own guidance is that using a payment service such as "Google Play's billing system" to complete transactions does not require declaring the data that service collects in connection with its processing — and this app contains no payment code at all, so it receives nothing either way. Re-read that if a Billing dependency is ever added (step 9); the app's own answers would still be "no", but the purchase handling would move into the app and the answers would need a fresh look.
-
Confirm the permission set the Console will show. [code] done 2026-10-13:
aapt2 dump badgingon the release APK reports exactly the table below (plus…DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION) — and noINTERNET. Re-check from the merged release manifest rather than the source one after any dependency change, so nothing a library quietly adds slips past:| Declared permission | Why | From | |---|---|---| | `READ_MEDIA_IMAGES` | read the photo library | app | | `READ_MEDIA_VISUAL_USER_SELECTED` | Android 14 partial access | app | | `READ_EXTERNAL_STORAGE` (`maxSdkVersion=32`) | same, on Android ≤ 12 | app | | `WRITE_EXTERNAL_STORAGE` (`maxSdkVersion=29`) | legacy delete on Android 10 only | app | | `FOREGROUND_SERVICE`, `FOREGROUND_SERVICE_DATA_SYNC` | keep a scan alive | app | | `POST_NOTIFICATIONS` | scan-progress notification | app | | `…DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` | framework-generated, not user-facing | AndroidX | Deliberately **absent**: `INTERNET` and `MANAGE_EXTERNAL_STORAGE`. Both are load-bearing for the "nothing leaves the device" claim, so re-check after any new dependency: ```bash ./gradlew :app:processReleaseMainManifest grep -A1 '<uses-permission' \ app/build/intermediates/merged_manifests/release/processReleaseManifest/AndroidManifest.xml \ | grep -oE 'android.permission.[A-Z_]+' | sort -u ``` (Match `<uses-permission` only. A bare `android.permission.` grep also picks up `android.permission.DUMP`, which AndroidX puts on its profile-installer *receiver* — a component restriction, not a permission the app requests.) -
Answer the Photo and video permissions declaration in the Console. The app requests
READ_MEDIA_IMAGES(plusREAD_MEDIA_VISUAL_USER_SELECTEDfor Android 14 partial access) and deletes only user-selected files through the system dialog. Paste:> Foto Dup Finder is a photo-cleanup tool. Reading the photo library **is** its core > functionality: it compares photos on the device to find exact and near duplicates > and lets the user remove the copies they select. Nothing is uploaded — the app > declares no network permission. Deletion always goes through the system consent > dialog (`MediaStore.createDeleteRequest`); the app never requests > `MANAGE_EXTERNAL_STORAGE`. -
Declare the foreground service type. This is the release-blocking item for the Android 14+ review. [code] The manifest already matches what you will declare:
| Where | Value | |---|---| | `AndroidManifest.xml` | `<uses-permission android:name="android.permission.FOREGROUND_SERVICE_DATA_SYNC" />` | | `AndroidManifest.xml` | `<service android:name=".service.ScanService" android:foregroundServiceType="dataSync" android:exported="false" />` | | `ScanService.kt` | `ServiceCompat.startForeground(…, ServiceInfo.FOREGROUND_SERVICE_TYPE_DATA_SYNC)` | | `ScanService.kt` | `onTimeout()` stops the scan at Android 15's 6-hour `dataSync` cap | The declaration page asks for **four** things per type, not one. Go to **App content › Foreground service permissions**: 1. **Description** of the app functionality using the type: > The app finds duplicate photos on the device. The user starts a scan and may leave > the app while it runs; the foreground service keeps that user-initiated scan alive > and shows its progress. The scan reads the photo library and writes a small local > index of file hashes. It performs no network access and transfers no data. 2. **User impact if the task is deferred or interrupted.** A scan is not deferrable work — the user is watching for a result — so there is no WorkManager/JobScheduler fallback: > If the scan were deferred, tapping "Start scan" would appear to do nothing and the > user would have to keep the app open for the work to begin at all. If it were > interrupted, the user would lose the progress of a whole-library comparison and > have to start again. Only reads are involved, so an interruption cannot lose or > corrupt data; the service stops as soon as the scan finishes or is cancelled, and > it is held only for the duration of the scan. 3. **Use case**: **Local processing › Other.** The Console puts three options under *Local processing*, and the other two do not describe this app. *Media transcoding* means converting media into a different format — the app writes no media file at all, it only reads photos to hash and compare them. *Importing, exporting* means moving files in or out of the app — the app's only write is its own private index of file hashes, which no other app ever sees. Play's wording for *Other* is *"Use for specifically user-initiated work and not for regular system or server-initiated tasks"*, which is exactly a scan the user taps *Start scan* for. This is not a cosmetic choice: an inaccurate use case is a misdeclaration, and the description and the video have to back up whichever option is picked — "reads the photo library and writes a small local index of file hashes" only fits *Other*. 4. **A link to a video** demonstrating the feature — *"The video should demonstrate the steps the user needs to take in your app in order to trigger the feature."* **Recorded on the test device** (Android 12 / MIUI, `2a2ae895`) on 2026-10-14 with: ```bash INSTALL=0 WARMUP=0 ./tools/record-fgs-demo.sh 2a2ae895 ``` The output is `store-assets/fgs-demo/foreground-service-demo.mp4` (**committed**, so it is already published; the checkpoint PNG per milestone beside it stays git-ignored). It was checked frame by frame afterwards rather than assumed: the intro at 0 s, the scan starting (*"Comparing file signatures… 91/102"*, 8 s), the shade held open for ~6 s with the live notification (*"Finding duplicate photos / Looking for visually similar photos… / CANCEL"*, 13–18 s) while the scan kept running behind it, and the finished results (*17 duplicate groups · 54 of 5,385 photos*) at the end. **The link to paste** is the file's page in Gitea — what the repository's own *view* of the file opens, and what plays it: ``` https://gitea.softwareapp-hb.de/fishfacegit/foto-duplicate-finder/src/branch/main/store-assets/fgs-demo/foreground-service-demo.mp4 ``` ⚠️ **Not the `/raw/` URL**, even though that is the file itself. Gitea answers raw responses with `Content-Security-Policy: default-src 'none'; style-src 'unsafe-inline'; sandbox` — a deliberate guard against raw HTML and SVG — and that blocks the media load of a document that navigates straight to a video: the tab stays blank with no error, which is exactly how this behaved in a browser. The same URL is fine as a *subresource*: the page above embeds `<video controls src="…/raw/branch/main/…mp4">`, which is why previewing the file plays it and opening `/raw/` does not. Use `/raw/` for `curl` and downloads, never as the link in the form. Verified about the **page** URL: **200** anonymously, containing that `<video controls>` element. Verified about the **raw** URL, from outside this network and unauthenticated: **200**, `Content-Type: video/mp4`, `Content-Length: 1847900`, `Content-Disposition: inline`, bytes sha256-identical to the recording, and `Range: bytes=0-99` → **206** with exactly those 100 bytes although `Accept-Ranges` is not advertised (which matters because `screenrecord` writes the `moov` atom at the very end of the file). Two things to know before pasting: the URL is pinned to `main`, so a re-shoot has to **overwrite the file in place** rather than be added alongside it; and replacing the video at all means resubmitting the declaration. If a link with no Gitea chrome around the player is preferred later, there are two ways and neither is needed for the declaration: an unlisted YouTube upload of the same file, or a rule on the Gitea host's Caddy proxy dropping the header for this one path (`@fgsdemo path …/store-assets/fgs-demo/*.mp4` plus `header_down @fgsdemo -Content-Security-Policy`) — **scoped to `store-assets/` only**, since that header is what makes raw HTML and SVG safe to serve. Neither was tried from here. Both flags exist because this take found two traps worth knowing before a re-shoot: - **`WARMUP=0` keeps the *cold* scan on camera.** A warm scan of this library takes **5.4 s**, which is less than the notification shade takes to open — so the first take filmed an empty shade, convincingly. The cold first scan (~20 s) is what gives the shade time to appear while the notification is still live, and reinstalling the app restores that window. - **`INSTALL=0` skips the install**, because MIUI does not let `adb` install anything: the command **hangs** waiting for two prompts on the device — Google Play Protect (*"App zum Sicherheitsscan senden?"*) and then MIUI's own *Installieren* — and auto-cancels as `INSTALL_FAILED_USER_RESTRICTED` if they go unanswered. The simplest route is to install once by hand and then record with `INSTALL=0`. A hand recording is just as valid and needs no tooling: every Android 11+ phone has a screen recorder in the quick settings, and the whole video is six steps — the intro, tap *Start scan* (the trigger the declaration asks to see), press Home, pull the shade down and leave the notification sitting there while the scan runs, tap the app back for the results, stop. Under two minutes and uncut: a reviewer has to be able to follow the trigger and see the service still working once the app has left the screen. ⚠️ **MIUI blocks synthetic input until the matching developer option is on.** Every `adb shell input tap` on this phone fails with *"Injecting to another application requires INJECT_EVENTS permission"* — which is why the project's earlier captures were all taken by hand. With **USB debugging** enabled (and the security-settings toggle that comes with it) the block lifts, `tools/record-fgs-demo.sh` drives the phone end to end and nothing is needed from a human. Toggling it resets the USB connection, though: the device comes back on a **new** `/dev/bus/usb` node, which has to be made readable before `adb` sees it again. ⚠️ **It cannot be recorded on a KVM-less emulator**, and the failure is the platform's, not the app's: every scan start there ends in `am_crash … ForegroundServiceDidNotStartInTimeException` → *Force finishing activity*, with no `am_kill` or low-memory record, because software emulation is too slow to get from `startForegroundService()` to `startForeground()` inside Android's budget. QEMU's virtual instruction counter dilates the guest clock and made it work exactly once (`-qemu -icount shift=1,sleep=off`, guest clock measured 2.30× slow) but not reproducibly, so that is a lead rather than a recipe; `SETTLE_SECONDS` / `WARM_SECONDS` scale this script's waits if it is ever retried. The declaration is **per type**: if a new foreground-service type is ever added to the manifest, it has to be declared here too. -

6. Testing before production
- Create an internal testing track and add yourself as a tester; install via the Play link on a real device.
- Test on the oldest supported Android version you can (minSdk 26) and on the newest you have (Android 16 / API 36).
- Test the permission flows:
- Deny access — app must not crash and must explain what is needed.
- Android 14+ partial access ("Select photos") — banner appears and the app scans the subset.
- Grant full access — scan works.
- Test deletion:
- Move to trash (Android 11+).
- Permanent delete (Android 11+).
- Refuse the system dialog — nothing is deleted, the app says so.
- Test with a library of several thousand photos to sanity-check scan time. [code] done on the test device: the 5,363-photo library scans in 20.2 s cold / 11.0 s warm, and the screenshot run over 5,385 photos finished in 11.1 s (6 unreadable files skipped).
- Verify no crashes in Play Console > Quality > Android vitals after rollout.
7. Release notes ("What's new") and rollout
⚠️ Which block applies first: versionCode is already 2 (versionName 1.0.1), because
1.0.1 was cut before anything reached Play — so the first upload is 1.0.1 and takes the
initial release block. The 1.0.1 block below applies only once 1.0.0 exists on a track.
Release notes are not stored in this repo — they are typed into the Play Console for each release.
Where:
- Production: Test and release > Production, then Create new release
- Testing: Test and release > Testing > Internal / Closed / Open testing
Rules (per Google's Prepare and roll out a release guide):
- Up to 500 Unicode characters per language.
- Language tags go on their own line, wrapping the text — a block starts with a line
containing
<en-US>and ends with a line containing</en-US>. Several<lang>blocks can be entered together. - Notes belong to a release, so every track has its own; "Copy from a previous release" avoids retyping.
- Google explicitly forbids using release notes for promotion or to solicit user actions — keep them factual about what changed.
- For app updates list only user-visible changes; the full developer history belongs in CHANGELOG.md.
Ready-to-paste block for the first release:
<en-US>
Initial release.
• Finds exact and near-duplicate photos
• Suggests which copy to keep
• Moves photos to the trash or deletes them via the system dialog
• No ads, no account, works fully offline
</en-US>
Ready-to-paste block for 1.0.1 (the scan-robustness patch):
<en-US>
• Fixed a scan that could appear to stop on very large photo libraries
• The app now recovers gracefully when the photo library is temporarily unresponsive
</en-US>
- Upload the
.aab, paste the notes above, and roll out to internal → closed → production (staged rollout recommended). - Monitor Android vitals and reviews; respond to feedback.
8. Post-launch maintenance
- Play requires new apps/updates to target recent API levels (API 36 from
August 2026 [code]). Re-check this requirement each year and bump
targetSdk. - Watch for newer AGP; when it supports it, update
compileSdkto 37 and bump the Compose BOM and Coil together (see the version note in the README). - Optionally add crash reporting later — but note this would change the Data safety answers, so weigh it against the "no data leaves the device" promise.
9. Monetisation — decided: one-time paid app, no billing
The decision is made: Foto Dup Finder is a one-time paid app (rationale, the €2.99 base price, the €1.49 launch sale and the irreversibility rule: STORE_LISTING › App pricing). The Console work is in step 4; nothing in this repository changes, because a price on the listing adds no code, no permission and no Data Safety answer — which is exactly what a free app with a Pro unlock could not claim.
Standing rules:
- Ads: never. Every ad SDK needs the
INTERNETpermission to fetch anything, and the merged-manifest check in step 5, PRIVACY.md and the Data Safety answers all rest on that permission being absent. - In-app purchases: deliberately absent. If that ever changes, the requirement is Play Billing
8+ (latest published: 9.1.0, with an extension available to Nov 1, 2026). Worth knowing before
the decision is re-litigated: the Billing Library itself does not add
INTERNET—com.android.billingclient:billing:9.1.0's manifest declares onlycom.android.vending.BILLINGand<queries>for the billing service, which was checked by unpacking the AAR. What would change is the store copy (the "pay once" line),PRIVACY.md, the acknowledgement/restore flow, and the fact that a purchase can only be verified on an internal testing track — never locally. - Refunds and support follow Play's policy for a paid app; keep the contact address in PRIVACY.md current.
