Dupe scans your iPhone Photos library entirely on your device. Photos, videos, and the fingerprints we compute from them never leave your phone. We don’t collect personal data — no account, no email, no analytics that identify you. Purchases are processed by Apple and our subscription provider (RevenueCat) using anonymous identifiers. That’s the whole story; the rest of this page is the detail.
The App is made by Workshop Operations Ltd, trading as General Software, a company registered in England and Wales (No. 14842982). We are the data controller for any personal data this policy describes.

To find duplicate and near-duplicate photos and videos, the App needs to read your Photos library. iOS asks you for permission the first time it needs access — you can grant Full Access, Limited Access, or refuse. You can change this at any time in Settings → Privacy & Security → Photos → Dupe.
When the App runs a scan, it:
Nothing produced by the scan ever leaves your device. We do not upload your photos, your videos, your fingerprints, any thumbnails, or any list of what was in your library to our servers or to any third party.
The App itself sends very little to us. The categories are:
If you subscribe to Dupe Unlimited, the purchase is processed by the Apple App Store. We use RevenueCat as a subscription middleware to track entitlement status (have you bought it? when does the period end?). RevenueCat sees an anonymous user identifier (App-generated UUID), your country code, your platform, and the transaction event — not your name, email, or any photo data. Apple separately holds your payment details; we never see them.
If you opt in to sharing analytics with developers in Settings → Privacy & Security → Analytics & Improvements, Apple may send us anonymous crash logs and basic performance metrics. These reports are aggregated and don’t identify you. If you have not opted in with Apple, we get nothing.
The App keeps internal counts on your device — how many duplicates you’ve cleared, how much storage you’ve reclaimed, your streak — to power the Stats and Achievements features. These numbers stay on your device and are deleted with the App.
We only use the third-party services strictly necessary to run the App:
We do not sell or share data with anyone else. We have no marketing, advertising, or data-broker partnerships.
The App does not engage in “tracking” as defined by Apple’s App Tracking Transparency framework. We never ask for permission to track you because we don’t. There are no ads in the App and we don’t use any advertising or marketing analytics SDKs.
Because we collect so little, most of the controls live in iOS itself:
If you’re in the UK, EU, EEA, Switzerland, California, or any other jurisdiction with data-protection rights, you can ask us to: confirm what (if anything) we hold on you; provide a copy; correct it; delete it; restrict or object to its processing; or take a portable copy. Email hello@general.software and we’ll respond within 30 days.
You also have the right to lodge a complaint with a data-protection authority — for example the UK ICO at ico.org.uk.
The App is not directed at children under 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal data from children. If you believe a child has provided data to us, contact hello@general.software and we’ll act promptly.
We’re based in the UK. Apple and RevenueCat are based in the United States and may process data in the US or other countries. By using the App you understand that your purchase data may be transferred to and processed in countries outside your own, with appropriate safeguards (such as Standard Contractual Clauses or equivalent) where required by law.
We update this policy when our practices change or when the law tells us to. The “Last updated” date at the top reflects the latest version. Material changes will be highlighted in-app before they take effect.
Privacy questions, data requests, anything else — email hello@general.software.
