Privacy Policy

Campfire OS · Last updated 30 August 2026

This Privacy Policy explains how Campfire OS ("the App," "we," "us," or "our"), published by Viva Apps Yazılım ve Danışmanlık Sanayi ve Ticaret Limited Şirketi, handles information when you use the App. We have designed Campfire OS to keep your data on your device. We do not require an account, and we do not sell your personal information.

1. Information we do not collect

Campfire OS does not require you to create an account or provide your name, email address, or phone number. We do not include advertising, analytics, or third-party tracking software in the App. We do not track you across other apps or websites.

2. Motion & orientation

Campfire OS uses your device's motion and orientation sensors to detect when your phone is placed face-down, which is what drives a focus session. This sensor data is processed only on your device in real time to run the session. It is not recorded, transmitted to us, or shared with third parties.

3. Screen Time & app shielding

If you choose to shield apps during a session, Campfire OS uses Apple's Screen Time (Family Controls) framework. The apps and categories you select are represented by opaque tokens provided by Apple and are stored on your device. Campfire OS cannot see your usage history or the identities of your apps beyond what Apple's framework exposes, and this information is not sent to us.

4. Information stored on your device

The data you create in Campfire OS — including your focus-session history, streaks, selected atmosphere, and preferences — is stored locally on your device. This information is not transmitted to us and is not uploaded to our servers.

5. iCloud sync

If you enable iCloud sync (a Pro feature), your session data is stored in your own private iCloud account using Apple's iCloud services, so it can sync across your devices. This data lives in your iCloud account under your control, not on our servers. Apple's handling of iCloud data is governed by Apple's privacy policy. You can turn sync off at any time in the App.

6. Notifications

If you enable notifications, these are scheduled as local notifications on your device. We do not operate a server that sends push notifications to you, and enabling notifications does not send any information to us.

7. Purchases and subscriptions

Campfire OS offers an optional paid upgrade, "Campfire Pro," through Apple's In-App Purchase system. Purchases are processed by Apple. We do not receive or store your payment card details.

To manage and verify your purchase and subscription status, we use RevenueCat, a third-party purchase-management service. When you make or restore a purchase, RevenueCat may process transaction information and anonymous or pseudonymous identifiers (such as a device-generated app user ID and Apple-provided purchase receipts) in order to determine whether your Pro entitlement is active. We use this only to unlock the features you have paid for.

8. How we use information

We use the limited information described above only to:

• Provide the App's core features (focus sessions, app shielding, streaks, and atmospheres).
• Detect device orientation on your device to run a session.
• Process, restore, and verify your purchases and subscription status.
• Maintain the security and proper functioning of the App.

We do not use your information for advertising or profiling.

9. Sharing of information

We do not sell, rent, or trade your personal information. Information is shared only with the service providers necessary to operate the App's paid features (Apple for payment processing and RevenueCat for purchase management), and only to the extent described above, or where required by law.

10. Children's privacy

Campfire OS is not directed to children under the age of 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can address it.

11. Your rights

Because your content is stored on your device (and, if you enable it, in your own iCloud account) and we do not maintain user accounts, you can remove your data at any time by deleting it within the App or by deleting the App. Depending on where you live, you may have rights to access, correct, or delete personal information processed on your behalf; to exercise these, contact us using the details below.

12. Data security

We rely on the security features of your device and of Apple's platform to protect data stored locally and in iCloud. While no method of storage or transmission is completely secure, we take reasonable measures to protect the limited information involved in operating the App.

13. 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. Continued use of the App after an update means you accept the revised policy.
