Privacy Policy

Effective 8 August 2026 · Trine is operated by FA Technologies ("we", "us"). Contact: support@trytrine.com

Trine is an astrology-first calendar app for iOS, currently in development, and this website. This policy describes what we collect, why, and the choices you have. The short version: we collect the minimum, we encrypt what is sensitive, we sell nothing, and deleting your account deletes your data.

On this website

This website collects no personal data: no accounts, no forms, no advertising trackers. If you email us, we use your address only to reply.

In the app (at launch)

• Account: your email address or Sign in with Apple identifier, used to operate your account.
• Birth details: birth date, time (optional), and birthplace, used solely to compute your astrological chart and the readings and recommendations derived from it. Birth details are encrypted at rest with a per-user key, are never included in analytics or logs, and are never sold, rented, or shared with advertisers. When you connect with another Trine user, they see a computed compatibility summary — never your birth details. Consent is per-connection and revocable; revoking deletes the derived data.
• Calendar data: with your permission, Trine reads the calendars on your device (via iOS EventKit) to display your events and find free time. This calendar data is processed on your device and is not uploaded to our servers, except the specific events you ask Trine to create. You can revoke calendar access at any time in system settings.
• Purchases: subscriptions are processed by Apple and our subscription provider RevenueCat. We receive purchase state, never your payment card.
• Product analytics and crash reports: we use PostHog (usage events, e.g. "opened week view") and Sentry (crash reports) to improve Trine. Birth details, chart placements, and calendar contents are excluded from both.

Google Calendar data

A future version of Trine will offer an optional connection to Google Calendar. If you connect it: we will access your calendar list and events (read) and create single events you explicitly schedule (write); we will use that data only to display your calendar inside Trine and to find free time for scheduling; we will store only sync metadata and the events needed to render your calendar, encrypted in transit and at rest; and we will share it with no one. Trine's use of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. Google Calendar data is never used for advertising, never sold, and never used to train machine-learning models.

Retention and deletion

We keep your data while your account exists. Deleting your account — available in the app and by emailing support@trytrine.com — permanently deletes your account data, and destroys the encryption key protecting your birth details, rendering them unrecoverable.

Your rights

Depending on where you live (including under GDPR and CCPA), you may have rights to access, correct, export, or delete your personal data, and to object to processing. Email us and we will honor them. We do not sell personal information as defined by the CCPA.

Children

Trine is not directed at children under 13 and we do not knowingly collect their data.

Changes

We will post any changes here with a new effective date, and notify you in the app if the changes are material.
