Play Store listing (M10)

Ready-to-paste copy for the Main store listing page, plus the graphics that go with it. Every graphic is generated from the app's own vectors, so a rebrand is a re-run rather than a redraw.

See PLAY_RELEASE_CHECKLIST § 6 for where this fits in the release.

App name

Plain Files

Deliberately not "File Manager": dozens of apps are literally called that, and a distinctive name is what makes a listing findable and rememberable. It is one string (app_name in values/strings.xml); the applicationId is separate and already locked.

Graphics

./tools/make-store-assets.sh                          # icon + feature graphic -> store-assets/
./tools/make-store-screenshots.sh                     # phone    -> screenshots/phone/
FORM_FACTOR=tablet-7in  ./tools/make-store-screenshots.sh
FORM_FACTOR=tablet-10in ./tools/make-store-screenshots.sh

Screenshots

Play's slots, and what each needs:

Slot	How many	Target here	Notes
Phone	2–8	`screenshots/phone/` — 1080×2160	A phone at its native 1080×2400 is 2.22:1 and is rejected; the normaliser crops chrome and clamps to 2:1
7-inch tablet	4+ recommended	`screenshots/tablet-7in/` — 1200×1920	A tablet frame is already inside the 2:1 cap, so 0 px of crop
10-inch tablet	4+ recommended	`screenshots/tablet-10in/` — 2560×1600	Landscape profile (matches the `tablet10` AVD); Play accepts either orientation

The library the shots are taken over

Never shoot over a real device's storage. Published screenshots are public, and a file list exposes real folder names and document titles. The library is generated instead:

python3 tools/make-demo-library.py        # -> demo-files/ (git-ignored, ~161 MB)
adb push demo-files /sdcard/Download/PlainFiles-Demo

tools/make-demo-library.py builds eight distinct sample images (so the grid view and thumbnails have something to show), a handful of documents, sized stand-ins for video and audio so the storage-usage screen has something worth ranking, and a real ZIP so the extract action can be exercised. Every name and every pixel is fake by construction.

Asset	Play's spec	Result	Source
App icon	512×512, 32-bit PNG with alpha, ≤ 1 MB	`store-assets/icon-512.png` — 512×512, RGBA, ~5 KB	`tools/store-assets/icon.svg`, mirroring `ic_launcher_background.xml` + `ic_launcher_foreground.xml`. Background, paths and opacities are identical, so the store icon is the launcher icon rather than a lookalike that drifts.
Feature graphic	1024×500, JPEG or 24-bit PNG without alpha	`store-assets/feature-graphic-1024x500.png` — 1024×500, RGB	`tools/store-assets/feature-graphic.svg`
Phone screenshots	no alpha, shorter side ≥ 320, longer side ≤ 3840, longer side ≤ 2× shorter	`store-assets/screenshots/phone/` (1080×2160)	`tools/make-store-screenshots.sh`, from `adb` captures in `store-assets/raw-screenshots/phone/`

Two details worth keeping:

The icon is full bleed. The background rect covers all 108 dp, so every pixel is opaque and Play's mask can crop to any shape without showing a gap.
A phone at its native 1080×2400 is 2.22:1 and is therefore rejected. The normaliser crops the status and navigation bars and then clamps to 1080×2160 — system chrome only, never app content. Tablets are already inside the 2:1 cap, so their crop defaults to 0.

The feature graphic's safe area

Play crops the feature graphic to a centre square for some placements, so all of the copy sits inside x 262…762 and the motif — which does not survive — is decoration. Verified by actually cropping the rendered PNG rather than by trusting the arithmetic:

magick store-assets/feature-graphic-1024x500.png -gravity Center -crop 500x500+0+0 +repage /tmp/square.png

Full description (4000 characters max)

Plain Files is a straightforward file manager for Android — no ads, no account, no
subscription, and no network access at all. You buy it once and it is yours.

BROWSE ANYTHING
• Internal storage, SD cards and USB drives, side by side
• List or grid view, with sorting by name, size, date or type
• Breadcrumb navigation and an in-folder search
• Hidden files on request

MANAGE YOUR FILES
• Copy, move, rename and delete, one item or many at once
• Create folders and edit text files in the built-in editor
• See the details of anything: size, type, location, modified date
• Open a file in any app, or share it

FIND OUT WHERE THE SPACE WENT
• A storage-usage view that measures every folder and ranks it largest first
• Spot the folder that is actually eating your storage, then act on it

ARCHIVES
• Create ZIP archives, and extract ZIP, TAR, TAR.GZ, GZ, BZ2 and XZ
• RAR and 7z are not supported — they need native code this app does not ship, and it says
  so rather than failing with a strange error

PRIVATE BY DEFAULT
• No INTERNET permission. The app cannot send your data anywhere, because it has no way to.
• No analytics, no advertising SDKs, no third-party trackers
• No account, no sign-in, nothing to remember
• Your files stay on your device, always

SOLD ONCE
• One purchase, every feature, no ads and nothing to buy inside the app
• No subscription

PERMISSIONS, EXPLAINED
Plain Files asks for "All files access" because that is what browsing and managing files
anywhere on a device requires — the app's core purpose. Google Play only grants this
permission to app types that genuinely need it, and a file manager is one of them. If you
would rather not grant it, the app still works: it can browse a folder you pick yourself
through Android's own folder picker, and it remembers that choice.

Read the privacy policy: https://example.invalid/plain-files/privacy

Replace the privacy-policy URL with the real public URL before publishing — a repository file is not acceptable to Play. PRIVACY.md is the source text.

Why the permission sentence matters

Play requires that an app's core functionality be prominently documented and promoted in the app's description when it declares MANAGE_EXTERNAL_STORAGE. The "PERMISSIONS, EXPLAINED" section is not marketing copy — it is the evidence the Permissions Declaration Form asks for.

Still to do before publishing

Screenshots. tools/make-store-screenshots.sh is written and the raw-screenshot directories are in place, but no captures have been taken yet, so store-assets/screenshots/ is empty. Capture against a synthetic library — never a real one, since published screenshots would expose real file names.
Tablet screenshots. Play has a 7-inch and a 10-inch slot, each wanting 4+.
