Terms of use

1. What you're agreeing to

By installing or using Saydence ("the app") you agree to these terms. If you don't agree, don't use the app. These terms apply to the free tier and to any paid subscription tier offered through the Apple App Store or Google Play.

2. What the app does

Saydence analyses text you provide using a rule-based engine that runs on your device. The paid tier adds AI-powered analysis through a backend proxy. See the Privacy policy for details on data handling.

3. Investigative aid only — not a lie detector

Saydence surfaces linguistic indicators associated with deception research frameworks (SCAN, SVA / CBCA, Reality Monitoring). Output is an investigative aid:

• It is not evidence of truthfulness or deception.
• It is not a substitute for professional assessment by trained investigators, psychologists, or legal counsel.
• The empirical validity of the underlying frameworks (SCAN especially) is contested in academic literature.

You agree not to rely on Saydence's output as a sole basis for any decision that materially affects another person — hiring, legal action, custody, accusations, or similar.

4. Acceptable use

You agree not to:

• Use the app to harass, defame, or threaten any person.
• Submit text you do not have the right to process (e.g. private communications obtained without consent in jurisdictions where that would be unlawful).
• Attempt to reverse engineer, scrape, or abuse the paid-tier AI proxy beyond fair-use limits.
• Resell or sublicense the app or its output without permission.

5. Subscriptions and billing

Paid subscriptions are managed by the store you bought them from — the Apple App Store on iOS or Google Play on Android — not by us. Billing, renewals, refunds, and cancellations follow that store's standard terms. You can cancel any active subscription at any time — on iOS via Settings → your Apple Account → Subscriptions, on Android via the Google Play Store → Subscriptions; cancellation takes effect at the end of the current paid period.

Pricing shown in the app reflects the regional pricing set by the App Store / Google Play. Subscription tiers and limits (analyses per month, character cap) are subject to change with prior notice; existing subscribers will not be downgraded mid-period.

6. No warranty

The app is provided "as is" without warranty of any kind, express or implied. We do not warrant that the app is error-free, that the rule engine output is accurate, or that the app will be available without interruption.

7. Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect, incidental, special, consequential, or punitive damages arising out of your use of the app — including but not limited to damages resulting from decisions you made based on the app's output.

Where liability cannot be excluded by law (for example, certain consumer rights in your jurisdiction), our total liability is limited to the amount you paid for the app in the twelve months preceding the claim.

8. Changes to these terms

We may update these terms when the app's functionality, pricing, or legal obligations change. Material changes will be announced in-app and reflected by a new effective date above. Continued use after changes constitutes acceptance.
