Effective 18 September 2026
Tempus is made by Crescere Studios (“we”, “us”). This policy says what Tempus collects, why, where it goes, and how to remove it. It is written to be read, not skimmed: the whole thing is short.
Account. When you sign in with Apple, Google or an email address, we store the name and email address the provider gives us, and the provider’s stable identifier for you. Signing in with an email address alone creates no server account: the address stays on your phone.
Backup. If you sign in with Apple or Google, Tempus copies its own data to our server so it can be restored: your miles balance, flight log, subjects, passes, card design, settings, and the name on your card. This is the same data the app keeps on your phone.
Shared bank. If you link banks with another member, the name you entered and the email address you sent the invitation to are stored so the invitation can be delivered, and both of you can see each other’s name and every movement of the shared pot. Nothing else about either of you is shared.
Gifts. A gift’s recipient name and email address are kept on your phone as part of your statement. They are not sent to us.
Purchases. Business Class is sold through Apple. Apple handles payment; we see whether the subscription is active, through RevenueCat, which processes the App Store receipt for us and assigns an anonymous identifier to your install. RevenueCat’s privacy policy is at https://www.revenuecat.com/privacy.
Screen Time. Tempus uses Apple’s Screen Time framework to block the apps you choose. Which apps you picked, and how long you used them, are held by iOS. The Tempus app cannot read them. The screen-time cards in the flight log are drawn by a separate extension that iOS runs, and it is not allowed to send anything back to the app or to us.
Motion. During a flight, Tempus reads the accelerometer to notice the phone being picked up. Readings are used on the spot and never stored or sent.
Face ID. Confirming a spend uses Apple’s Face ID or your passcode. Tempus only learns whether the check passed. It never has access to biometric data.
Notifications. Notifications are created on your phone. We run no notification server.
No advertising. No analytics. No tracking across apps or websites. No selling, renting or trading of personal information. No data brokers. No profiling.
Account and backup data is stored with Supabase, our hosting provider, and is protected so that each member can read and write only their own rows. Supabase’s privacy policy is at https://supabase.com/privacy. Data on your phone is stored in the app’s own container and, for the blocking features, in a container shared only with the Tempus extensions on the same phone. Sign-in credentials are kept in the iOS Keychain.
For as long as you have an account. A backup is overwritten each time the app saves, so we hold only the latest copy. When you delete your account, the account and every row tied to it are deleted immediately. A shared bank is unlinked first so the other member keeps their share.
If you are in Australia, the Privacy Act 1988 and the Australian Privacy Principles apply, and you may complain to the Office of the Australian Information Commissioner. If you are in the European Economic Area or the United Kingdom, you have the rights to access, rectify, erase, restrict and port your data, and to complain to your supervisory authority. Write to us first and we will sort it out.
Every connection is encrypted in transit. Server data is protected by per-member access rules enforced by the database itself, not by the app. Credentials never leave the Keychain. If a breach were ever to affect your personal information, we would tell you and the relevant authority as the law requires.
Tempus is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has created an account, contact us and we will delete it.
If this policy changes, the new version ships with the app and its effective date moves. Material changes will be pointed out in the app.
