Tierloom Privacy Policy
Summary
Tierloom is a tier list and ranking maker that works offline. There is no account, no sign-in, no analytics, no advertising, no crash reporting and no Tierloom server. Your boards and pictures stay on your device. The optional Tierloom Pro subscription is sold through Google Play, which handles the payment; see Tierloom Pro and Google Play Billing for the one connection the app makes to support it.
Data the app stores on your device
| Data | Where it lives | Why |
|---|---|---|
| Boards: titles, tier labels and colours, item captions, ordering | App-private storage on your device | So your boards are there when you reopen the app |
| Pictures you choose to add to a board | Copied (downsized to at most 1600 px) into the app's private folder, with a small thumbnail | So a board keeps its pictures even if the original file moves |
| Preferences (theme, welcome and tips shown, export defaults) | App-private storage | To remember your choices |
| Pro status: the date your free trial started, the latest time the app has seen on your device's clock, and the last subscription status reported by Google Play | App-private storage | To run the 30-day trial and to know whether Pro features are available |
Your original photos are only read when you pick them; Tierloom never modifies or deletes files in your photo library.
Tierloom Pro and Google Play Billing
Tierloom Pro is an optional yearly subscription sold through Google Play. Google Play processes the payment and holds your payment details; Tierloom never receives your card number, billing address or payment information.
The app uses the Google Play Billing Library, a Google component included in the app, only when you open the Tierloom Pro screen, when you tap Restore purchases, and, if you have or once had a subscription or a purchase is still being completed, when the app starts or you return to it (to check the subscription is active and to confirm a completed purchase with Google Play). The library talks to the Google Play Store app on your device to show the price, complete a purchase and report whether your subscription is active (for example the product, a purchase token and whether it renews). The Google Play Billing Library may also send Google diagnostic information about these billing operations. Google handles this information under the Google Privacy Policy.
Tierloom keeps the subscription status only on your device and does not send it, or anything else, to Binary Data Technology or to any other third party.
Data the app does not collect
Tierloom does not collect names, email addresses, contacts, location, advertising identifiers, usage analytics or crash reports, and it has no server to send them to. Apart from the Google Play Billing connection described above, the app makes no network requests of its own. The links in the app open this website or your email app.
Permissions
Tierloom requests no runtime permissions. Pictures are selected through the Android photo picker or document chooser, which hands the app only the pictures you select. Backups and exports are written through the system file chooser to the folder you pick. The app declares the Google Play billing permission, which lets it offer the Pro subscription; it does not give access to any of your data.
Sharing, exporting and backups
Exported images and backup files leave the device only when you choose Share or Save and pick a destination app or folder. The destination you pick then handles that file under its own privacy policy. A backup file contains your boards and the pictures in them; treat it like any personal file. Backups do not contain your Pro status or payment information.
Children
Tierloom is a general-audience utility intended for users aged 13 and older. It is not directed at children.
Data retention and deletion
Data stays on your device until you delete a board in the app or uninstall the app. Uninstalling removes all Tierloom data, including the Pro trial date. Android cloud backup of app data is disabled for Tierloom. Your subscription itself is managed by Google Play: you can view or cancel it in Google Play › Payments & subscriptions › Subscriptions. See the data deletion page for details.
Security
Data is held in Android's app-private storage, which other apps cannot read on an unmodified device. Because Tierloom has no server, there is no server-side copy of your boards to protect or breach.
Third parties
The app bundles no third-party analytics, advertising or tracking SDKs. It includes the Google Play Billing Library for the Pro subscription, as described above. Open-source libraries used to build the app (Expo, React Native and related packages) run on the device.
Changes
If a future version changes what data is collected, this policy and the in-app privacy screen will be updated before that version is released, and the Google Play Data safety section will be updated to match.
