1. The short version
Gantry does not sell your data, does not show ads, and does not use any third-party analytics or tracking. We collect the minimum needed to run your account and your missions. The list of apps you choose to block never leaves your device in a form anyone — including us — can read.
2. Information we collect
Account information
When you sign in with Sign in with Apple, we receive a unique Apple-provided identifier for your account. If you choose to share it, we also receive an email address, which may be Apple's private relay address rather than your real address. We do not receive your name unless you choose to provide it.
Mission data
To run the core feature, we store information about your missions: when a mission started and ended, whether it was completed or ended early, its duration, and a sequential mission number. This data is stored on your device and synced to our backend so it is available across your devices and not lost if you reinstall the app.
Your selected apps (Screen Time)
Gantry uses Apple's Family Controls and Screen Time frameworks to let you choose which apps to block during a mission. By Apple's design, when you pick apps, Apple gives Gantry only opaque, non-identifying tokens — not the names of the apps. Gantry never sees which specific apps you selected, and these tokens are meaningless outside your device. They are stored locally and are not transmitted to or readable by us.
Subscription information
Purchases are processed by Apple. We use RevenueCat, a subscription management provider, to determine whether your subscription is active. RevenueCat receives a pseudonymous app user identifier and transaction/receipt information from Apple in order to validate your subscription. We do not receive or store your full payment-card details — Apple handles payment processing.
Notifications
If you enable notifications, your device may provide a push token so we can deliver mission-related notifications, such as a completion alert. You can disable notifications at any time in iOS Settings.
What we do not collect
- No advertising identifiers and no ad networks.
- No third-party analytics or behavioral tracking SDKs.
- No location data.
- No contacts, photos, or browsing history.
- No record of which specific apps you block.
3. How we use information
We use the information described above only to:
- Create and maintain your account;
- Run, sync, and display your missions and mission history;
- Determine whether you have an active subscription;
- Send mission-related notifications you have enabled;
- Respond to support requests and keep the Service secure.
We do not use your information to build advertising profiles or to sell or rent it to anyone.
4. How information is shared
We do not sell your personal information. We share information only with the service providers that make Gantry work, and only as needed:
- Apple — for Sign in with Apple, Screen Time functionality, payment processing, and push notification delivery.
- Supabase — our backend provider, which hosts the database and authentication services that store your account and mission data.
- RevenueCat — which validates and reports your subscription status.
These providers process data on our behalf under their own privacy and security commitments. We may also disclose information if required by law, or to protect the rights, safety, and security of our users or the Service.
5. Data retention
We keep your account and mission data for as long as your account is active. If you delete your account, we delete the personal information associated with it from our systems within a reasonable period, except where we are required to retain certain records by law.
6. Your choices and rights
You can request access to, correction of, or deletion of your personal information by contacting us at ramie.chaarani@gmail.com. You can also delete your account from within the app, which removes your associated data as described above. Depending on where you live, you may have additional rights under laws such as the GDPR or the CCPA, including the right to object to certain processing or to lodge a complaint with a regulator.
7. Security
We use reasonable technical and organizational measures to protect your information, including encryption in transit and access controls on our backend. No method of transmission or storage is completely secure, however, and we cannot guarantee absolute security.
8. Children
Gantry is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us with personal information, contact us and we will delete it.
9. International users
Gantry is operated with the help of service providers that may store and process data in countries other than your own. Where that happens, we rely on those providers' safeguards for cross-border data transfers. By using the Service, you understand your information may be processed in those locations.
10. Changes to this policy
We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date above and, where the changes are material, provide a more prominent notice. Continued use of the Service after an update means you accept the revised policy.
