Your poker record stays yours.
The public app has no Internet permission.
Felt Stack sends no data to a developer endpoint, advertising service, analytics service, crash reporter, account service, or backend.
What stays on the phone
Session records, notes, settings, reviews, recognized text, and bankroll figures stay in the app's local storage unless the user starts an export, share, backup, import, or restore action.
Felt Stack has no account, server record, or developer-held data to delete.
Felt Stack uses no analytics, telemetry, or crash-reporting service.
What can leave when you choose
A user can deliberately hand an export or shared text to an app or storage provider they choose.
CSV export and backup run only after a user action and use Android's file picker for the destination.
Import and restore read only the file the user chooses.
Backups and device transfer
Backups may be password-encrypted with AES-256-GCM.
The password stays with the user and cannot be recovered by the developer.
The app also permits a plaintext backup after an explicit warning.
A successful restore keeps a safety copy in the app sandbox.
Automatic Android backup is disabled with android:allowBackup="false".
Cloud backup and device transfer exclude every valid app domain.
The same exclusions apply on older Android versions.
Android cloud restore and device transfer do not move Felt Stack data.
The user-controlled export and backup flows are the supported way to move it.
Speech recognition
The microphone button sends live audio to Android's configured speech recognition service.
Depending on the device, recognizer, network state, and OS settings, that service may process audio off the device.
Felt Stack does not control the recognizer's transport, storage, retention, or training behavior.
Felt Stack receives recognized text from the service.
The app stores recognized text only when the containing note or review is saved.
Felt Stack stores no microphone audio.
Deletion
Deleting a session, review, analysis, fact, or venue inside Felt Stack marks the row as deleted.
The row disappears from normal views and calculations, but its tombstone remains in the local database.
Full exports and backups preserve tombstones.
A file exported or backed up outside the app remains under the user's control and must be deleted there.
Launch-list data on this website
The launch-list form and its database run on Cloudflare Pages Functions and Cloudflare D1, on the same account that already serves this site.
A launch-list row holds your email address, the release state at submission, the exact consent sentence and its SHA-256, any optional Android model, play style and dictation-tester answers you give, and created, updated, and deleted timestamps.
A launch-list row holds no address of your device, no browser or device identifier, and no country, referrer, or timing fingerprint.
The launch-list address is used only to email you when Android testing or public access opens.
Launch-list rows are removed 90 days after public Android availability, or on request, whichever comes first.
A launch-list deletion request is a hard delete: the row is removed from the website database. That is the opposite of the in-app behaviour described in section 05 of the privacy page, where deleting inside Felt Stack leaves a tombstone in your local database.
Email support@feltstack.app to have your launch-list row deleted.
Submitting the form again after a deletion request puts you back on the list, because that is your own action.
The website runs no analytics, no tracking script, and no third-party embed.
The no-third-party-request and no-analytics statements on this site remain true and are re-asserted here. What changed is that the site now has a first-party form: when, and only when, a visitor submits it, the browser posts to feltstack.app and the row is stored in Cloudflare D1 on the same account that already hosts the site. Nothing is sent anywhere else, nothing is loaded from anywhere else, and no page reports anything on its own.
