Privacy Policy for File Type: Extension Lookup
Effective date: 14 November 2026
This Privacy Policy explains how File Type: Extension Lookup (“File Type”, “the app”, “we”, “us”) handles information when you use the app on iPhone or iPad. File Type is developed by Apurba Saha.
1. Summary
File Type is a reference app for looking up file extensions. It does not require an account, does not show advertising, and does not track you across other apps or websites. The extension database is built into the app, so searching and browsing work offline.
2. Information we do not collect
We do not collect, store or share:
Your name, email address, phone number or other contact details
Your location
Your contacts, photos, files or any other content on your device
The searches you make or the extensions you look up
Advertising identifiers (IDFA)
The app does not contain any advertising or analytics software development kits (SDKs) and does not use App Tracking Transparency, because no tracking takes place.
3. Optional in-app purchases (“Buy me a Coffee”)
The app offers optional in-app purchases that let you support its development. These purchases are processed entirely by Apple through the App Store. We never receive your payment card details, Apple ID or billing address.
To confirm and manage these purchases, the app uses RevenueCat, a third-party in-app purchase service. When you open the app or make a purchase, RevenueCat may process:
An anonymous app user ID generated randomly by the app (it is not linked to your name, email or Apple ID)
The App Store receipt or transaction information for purchases made in the app
Basic technical information such as device model, operating system version, app version, country or region, language setting, and the dates you first and last used the app
This information is used only to validate purchases, restore purchases and understand overall purchase activity. It is not used to identify you personally, is not used for advertising, and is not sold. RevenueCat’s handling of this data is described in its privacy policy: https://www.revenuecat.com/privacy
4. Links to websites
The app contains links to this Privacy Policy, our Terms of Service and our support page. These open in an in-app browser (Safari View Controller) and are hosted by Google Sites. When you visit them, Google may collect standard web information under its own privacy policy: https://policies.google.com/privacy
5. Data retention
We do not store any personal information ourselves. Purchase-related data processed by RevenueCat is kept in line with RevenueCat’s data retention practices. The extension database and your app settings stay on your device and are removed when you delete the app.
6. Data security
Communication between the app and RevenueCat or Apple is encrypted in transit using industry-standard HTTPS.
7. Children’s privacy
File Type is suitable for general audiences. We do not knowingly collect personal information from children. Because the app does not collect personal information, there is no personal data from children to access or delete. If you believe a child has provided personal information through the app, please contact us and we will help resolve it.
8. Your rights
Depending on where you live (for example, under the Australian Privacy Act, the EU/UK GDPR or the California CCPA), you may have the right to access, correct or delete personal information about you. Because File Type does not collect personal information that identifies you, in most cases we hold nothing to provide or delete. You can contact us with any request and we will respond within a reasonable time. You can also request deletion of purchase records held by RevenueCat by contacting us.
9. Changes to this policy
We may update this Privacy Policy from time to time, for example when we add new features. The updated version will be posted on this page with a new effective date. Significant changes will also be noted in the app’s update notes.
