One Spend Privacy Policy

Last updated: October 2026

One Spend ("the app") is a subscription and spending tracker made by Syed Arham Raza. This policy explains what the app collects and why.

Your data stays on your device

Everything you enter stays in the app's storage on your phone. That includes subscriptions, prices, notes, links, categories, payment cards and settings. There is no account and no sync, and the developer has no server that receives this information. For payment cards, only a nickname and the last 4 digits are stored, never a full card number.

Your data leaves the device only when you choose to share it, for example by saving a backup file or exporting a PDF, CSV, text or calendar file. It then goes only where you send it.

Crash reports and usage statistics

To find and fix bugs, the app uses two Google Firebase services:

• Firebase Crashlytics receives a crash report when the app crashes or hits an error. A report contains:
  • the technical error and where in the code it happened;
  • the app version;
  • the device model and Android version;
  • a short list of the screens and actions just before the error;
  • a few app settings: your main currency code, a rough size of your list (such as "6-20"), and whether reminders and 3D effects are on.
• Firebase Analytics receives anonymous usage statistics: which screens are opened and which features are used (for example "a subscription was added in the Music category" or "a backup was saved"). Analytics also works out an approximate location (country only) from your IP address; the IP address itself isn't stored.

These reports and statistics never include subscription names, prices, notes, links, custom category names, payment card details, or anything else you type into the app. Custom categories are recorded only as "custom".

Firebase uses a random installation ID to group events from the same install. It isn't linked to your name, email or any account. The app does not use the Android Advertising ID, shows no ads and does no ad attribution.

Google processes this data on the developer's behalf under the Firebase terms and Google's privacy policy. By default, Crashlytics keeps crash reports for 90 days and Analytics keeps data for up to 14 months.

Network access

Besides Firebase, the app connects to the internet only to:

• download currency exchange rates (no personal data is sent);
• check Google Play for app updates;
• open links you tap.

Children

The app isn't directed at children under 13 and doesn't knowingly collect their information.

Deleting your data

Uninstalling the app deletes everything stored on your device. Crash reports and statistics aren't linked to you, so they can't be looked up per person. They expire as described above.

Changes

If this policy changes, the new version will be published at the same address with a new date.
