Privacy Policy
This policy describes the app as it behaves today. When new features change how data is handled (for example, encryption at rest or optional backup), we will update this page before those changes ship.
The short version
Everything you write or say in My Secret Diary stays on your phone. We have no servers that receive your content, no accounts, and no analytics. We cannot read your diary because we never receive it.
What the app stores
Your diary entries, voice recordings (temporarily, until transcribed — then deleted by default), and app settings are stored only on your device, in the app's private storage. In this early release, that storage is protected by your device's standard app sandboxing; encryption at rest and a biometric app lock are planned and will be announced when they ship.
What leaves your device
Almost nothing, and never your content:
- AI model downloads. The app performs speech recognition and text generation entirely on your device using AI models. When — and only when — you explicitly tap to download a model, the app fetches it from the public Hugging Face model repository (huggingface.co). That download request is visible to Hugging Face and its CDN like any file download (your IP address requests a file). No personal data, diary content, or device identifiers are sent with it, and no download ever happens without your explicit action.
That is the app's only network activity. There is no telemetry, no crash reporting, no advertising, and no third-party analytics SDK.
Data we collect
None. We have no backend, no user database, and no way to identify you.
If you email us for support, we receive whatever you send — that is the only way we would ever hold information about you, and you can ask us to delete it at any time.
Your control over your data
Because your data never leaves your device:
- View, edit, delete: every entry can be viewed, edited, or deleted in the app.
- Delete everything: uninstalling the app deletes all app data.
- Portability: local export is on our roadmap; today your data lives only on your device.
Children
The app is intended for adults 18 and older and includes an age declaration at first launch. We do not knowingly provide the app to minors.
Microphone
The microphone is used only when you press record, and recordings are transcribed on your device. Audio is deleted after transcription unless you change the retention setting.
Changes to this policy
If a future version changes how data is handled (for example, optional encrypted backup), we will update this policy and describe the change in the app before it takes effect.
