Privacy policy

Effective 30 October 2026 · Applies to Stumbletown, MemoMix and Session Checklist

blimmin.ai (“we”) makes small apps. We collect only the data each app needs to work, we don't sell it, and we don't use it for advertising or cross-app tracking. This page covers every blimmin.ai app; the sections below list exactly what each one collects.

What applies to every app

  • No ads, no ad tracking. We don't use advertising SDKs or the Identifier for Advertisers.
  • Crash reports. We use Sentry to receive crash and error reports (device model, OS version, app version, the error itself). These are used only to fix bugs.
  • Service providers. Data is processed by the providers named below solely to run the app. They act on our instructions.
  • Retention. We keep account data while your account exists and delete it within 30 days of a deletion request.
  • Your rights. You can access, correct, export or delete your data at any time by emailing [email protected]. If you're in the UK or EU, you also have rights under GDPR, including the right to complain to your data protection authority (the ICO in the UK). California residents have equivalent rights under the CCPA.
  • Children. Our apps aren't directed at children under 13 and we don't knowingly collect their data.
