Privacy policy

What this app does

Saydence (Statement Analyser) analyses text you provide using a rule-based engine that runs entirely on your device. The engine examines linguistic patterns associated with research frameworks like SCAN, SVA and Reality Monitoring, and reports a credibility score and per-rule findings.

What data we collect — free tier

None. The app has no server-side component, does not include analytics SDKs that transmit your input, and does not send any data off your device. Network access is not required for analysis.

Camera and image OCR

If you use the Camera or Gallery / Photos option on the input screen, Saydence extracts text from the photo using on-device text recognition — Apple's Vision framework on iOS, Google's ML Kit on Android. Recognition runs entirely on your device — the image is never uploaded to Apple, Google, us, or any other server. Camera captures land in the app's private cache and are deleted immediately after OCR completes. Photo capture is handled by the system camera / photo picker; Saydence does not embed its own camera access.

What data we collect — paid AI tier

On the paid tier, an analysis you run with AI is handled by specialised AI models from selected partners. To do that, your statement is sent to the partner that runs the model, which processes it under its own privacy terms and returns the result. We keep no copy of it on our servers once the request is done, and we may change partners as the technology moves on. If that ever changes what happens to your data, we will update this policy and the date on it.

If your device is offline or the partner cannot be reached, the app falls back to the same analysis the free tier runs entirely on your phone, and it tells you the AI version could not finish this time. Your statement is never queued or sent later without you asking, so in that case nothing leaves the device.

What's stored on this device

We persist a few small things in this app's private storage:

• Your acknowledgement of the first-launch disclaimer (a single boolean).
• The current day's analysis count, used to enforce the free-tier daily cap.
• A list of up to 20 recent analyses — timestamp, your input text, score, and verdict — so you can re-open them from the Recents screen.
• Your theme preference (System / Light / Dark) and crash-reporting opt-in.

All of this lives in the app's sandboxed storage and is not readable by other apps. Use Settings → Delete all local data to wipe everything in one action. See also our data-deletion instructions.

What we don't collect

• We do not collect your name, email, or any personal identifier.
• We do not use analytics SDKs that ship your input text.
• We do not share data with third parties.
• Crash reporting is opt-in only and disabled by default.
• Saydence excludes its data from cloud backup and device transfer — it does not sync to iCloud or Google Drive, or migrate to a new device.

Reminder about what this app is

Statement Analyser surfaces linguistic indicators consistent with research frameworks. It does not detect lies. It is not evidence and is not a substitute for professional assessment. The empirical validity of the underlying frameworks (SCAN especially) is contested in academic literature — see the in-app glossary under Help for more.

Changes to this policy

If this policy changes in a way that materially affects what data we handle, the disclaimer will re-trigger on next launch and the date above will be updated.
