Fernwick - Privacy Policy
This Privacy Policy describes how Fernwick (the “App”) handles information. Please read it together with the App Privacy section on the App Store product page, which lists the same data categories.
1. What the App itself keeps on your device
The App is an offline focus timer. Everything you create while using it — your session history, your fern collection, unlocked species, streaks, totals, and your settings — is written to a single local file on your device. It is not sent to us and not synced anywhere.
- The App does not use a microphone, camera, or photo library. No recordings or photos are captured.
- Local notifications (session end, optional evening reminder) are scheduled through the system and stay on your device.
- Because this stays on your device, it is not part of the data categories listed in sections 2 and 3 below, and it is never uploaded.
2. Data collected and used to track you
The App includes third-party advertising and attribution software. The following data is collected, may be linked to you, and is used to track you — meaning it may be used to link your activity across this App and other apps and websites for advertising purposes, such as measuring ad performance and serving personalised ads.
| Data type | Linked to you | Used for |
|---|---|---|
| Device ID | Yes | Analytics, App Functionality, Developer’s Advertising, Third-Party Advertising |
| Advertising Data | Yes | Analytics, Developer’s Advertising, Third-Party Advertising |
| Product Interaction | Yes | Analytics, App Functionality, Developer’s Advertising, Third-Party Advertising |
| User ID | Yes | Third-Party Advertising |
| Coarse Location | Yes | Analytics, App Functionality, Developer’s Advertising, Third-Party Advertising |
| Performance Data | No | Analytics, App Functionality, Developer’s Advertising, Third-Party Advertising |
| Other Data | Yes | Analytics, App Functionality, Developer’s Advertising, Third-Party Advertising |
3. Data collected but not used to track you
The following data is collected but is not used to link your activity across other companies’ apps and websites.
| Data type | Linked to you | Used for |
|---|---|---|
| Crash Data | No | Analytics |
| Other Diagnostic Data | No | Analytics, App Functionality, Developer’s Advertising, Third-Party Advertising |
4. Third-party services we use
The App integrates the following third-party software. These providers collect the categories described in sections 2 and 3 under their own privacy policies.
- Adjust — mobile attribution and analytics, used to measure where installs and ad revenue come from.
Privacy policy: https://www.adjust.com/legal/privacy-policy - AppLovin MAX — an advertising mediation platform. MAX serves ads through its mediated third-party advertising networks, who may collect device and advertising data for their own purposes.
Privacy policy: https://www.applovin.com/privacy/
The list of mediated networks can change over time; AppLovin’s policy above is the authoritative source for who they share data with.
5. App Tracking Transparency (ATT)
The first time you launch the App, iOS shows the App Tracking Transparency prompt asking whether you allow the App to track your activity across other companies’ apps and websites.
- If you allow it, the advertising and attribution software may use the identifiers listed in section 2 to measure ad performance and personalise ads.
- If you do not allow it, that tracking is not performed through the advertising identifiers on your device. You still see ads; they are simply less personalised. The App keeps working either way.
- You can change your choice at any time in Settings → Privacy & Security → Tracking.
6. Deleting your data
Because your progress is stored only on your device, you can delete it yourself:
- In the App, open Settings → Reset all data and confirm. This erases your session history, fern collection, and settings, and returns the App to its initial state.
- Or delete the App from your device, which removes all of its local files.
Data already collected by the third-party services in section 4 is handled under their own policies; contact them directly if you want it removed.
7. Children
The App is a timer and is not directed at children. If you believe a child has provided information to us through the third-party services described above, contact us and we will follow up with those providers.
8. Changes to this policy
We may update this Privacy Policy from time to time. Updates will be posted on this page with a new date. If we add or remove third-party services or change what is collected, we will update both this page and the App Privacy section on the App Store product page.
