Privacy Policy

Last updated: 30 June 2026

Sentiscale ("Sentiscale", "we", "us") is operated by Vesper AI, c/o ExpertFid & Audit SA, Strehlgasse 2, 8001 Zürich, Switzerland (the "Operator"). This policy explains what the Sentiscale iOS app and its lock-screen widget collect, why, and the choices you have.

The short version: Sentiscale has no user accounts, shows the same market-wide information to everyone, serves no ads, and uses no third-party tracking or advertising SDKs. We collect only the minimum needed to deliver the notifications you ask for and to verify a Pro subscription.

What we collect

• Push notification token. If you enable notifications, Apple issues your device a push token, which we store so our server can send the alerts you choose.
• Notification preference. Your chosen tier (Off, Daily why, or All) is stored alongside that token.
• Subscription status. If you subscribe to Sentiscale Pro, the App Store gives the app an Apple-signed receipt. We verify it to unlock Pro features and keep a minimal record (the subscription's transaction identifier and expiry date) to confirm continued access and to honor refunds and cancellations. We never receive your name, payment card, or Apple ID — Apple handles all payment.
• Support messages. If you email us, we receive your message and address in order to reply.

We do not collect your name, an account, contacts, location, browsing history, or the device advertising identifier, and we do not use analytics or advertising SDKs.

How we use it

• To deliver the notifications you opt into.
• To verify a Pro subscription and unlock paid features.
• To respond to support requests.

We do not sell or rent your data, and we do not use it for advertising or profiling.

Market data

The gauge is derived from publicly available market and news data we retrieve from third-party sources (for example Finnhub, Cboe, and alternative.me). These are sources we read from; we do not send them any information about you.

Apple

Payments, subscription management, and push delivery are handled by Apple under Apple's own privacy policy.

Retention

We keep your push token and notification preference until the token becomes invalid, you turn notifications off, or you delete the app. Subscription verification records are kept for as long as needed to confirm entitlement and to meet legal and accounting obligations.

Your choices

• Turn notifications off in the app or in iOS Settings at any time.
• Manage or cancel your subscription in iOS Settings.
• Deleting the app stops any further collection.

Your rights

Depending on where you live (including under the Swiss FADP and the EU GDPR), you may have the right to access, correct, or delete your data, or to object to its processing. To exercise these rights, contact us at the address below.

Children

Sentiscale is not directed to children under 13 (or the minimum age in your country) and we do not knowingly collect their data.

Changes

We may update this policy. We will post the new version on this page and update the date above.
