Drill
Drill collects nothing. There is no account, no server run by us, no analytics and no advertising. We never see your cards. This page explains where your cards are stored, what a few optional features do, how to remove everything, and what rights you have if you live in the European Union, the EEA or the United Kingdom.
Your decks, cards, images, audio clips, flags and review history (which card you answered, when, and how) are stored in a database on your iPhone. If iCloud is on, Apple's CloudKit mirrors that whole database — cards, media and review history alike — into your private iCloud database, a space tied to your Apple ID that only your devices can read. We have no access to it and no way to get any. Turn it off in iPhone Settings › [your name] › iCloud.
Imports — .apkg packages, Drill's own zip, CSV and text files, Quizlet exports, Kindle clippings — are read on the device and stored like any other cards. Nothing is uploaded to read them.
Photos you add to a card come through the system photo picker, which hands Drill only the image you chose; Drill does not ask for access to your photo library. The image is copied into the card at a reduced size.
Audio clips are recorded only while you press Record, for at most sixty seconds, and are written into that card. iOS asks for microphone permission the first time; refusing it only turns that one feature off.
Reading a page from a photo uses Apple's on-device text recognition. The photograph is not kept; what lands in the app is the text that was read. Nothing leaves the iPhone.
Generating cards from a passage (Drill Pro) uses Apple Intelligence's on-device model. The passage and the cards it produces stay on the iPhone; Drill sends nothing to us or to any other server for this feature. It is only available on iPhones that support Apple Intelligence, and Drill says so when it is not.
The daily reminder is a local notification scheduled on your iPhone. Its text is a count — "24 cards are waiting" — and never a card's contents. It can appear on the lock screen like any notification.
The home-screen widget and the Live Activity (Drill Pro) show your streak, today's due count, deck names and a session's progress. They read a few numbers Drill writes to a shared area on the phone; they never show a card's text. Both can appear on the lock screen.
No account, no email, no sign-in. No analytics, no crash-reporting SDK, no advertising SDK, no third-party code. No tracking, and no App Tracking Transparency prompt — there is nothing to track. No reading, scanning or "AI" processing of your cards anywhere but on your own device.
When you share a deck, Drill writes a zip file and hands it to the iOS share sheet. Where it goes from there — AirDrop, Files, a message — is your choice and happens under that service's terms. Nothing passes through us.
Drill Pro is a one-time purchase handled entirely by Apple's App Store. Apple tells the app whether the purchase exists; Apple's own privacy policy covers the payment.
Settings › Delete all decks and cards removes every deck, card, image, clip and review record from the iPhone and from your iCloud database. Deleting the app removes everything on the phone. Your iCloud copy can also be removed from iPhone Settings › [your name] › iCloud › Manage Storage.
Drill is not directed at children under 13 and collects no personal data from anyone.
Who is responsible. Drill is published by PrimeTruth Team, an individual developer based in Vietnam, reachable at zenDesign219@gmail.com. Because Drill has no server of ours, your cards never travel to us: we cannot read them, copy them, hand them over or restore them for you.
What we actually process. The only personal data that ever reaches us is what you choose to put in an email to us — your address and whatever you write in it. We use it to answer you and keep it only as long as that takes. Our legal basis is our legitimate interest in replying to the people who write to us (Art. 6(1)(f) GDPR). Your cards themselves have no legal basis to speak of, because we never receive them; they live on your device and, if you switch iCloud on, in your own Apple account under Apple's terms.
Your rights. You may ask us for access to the data we hold about you, for it to be corrected or deleted, for its processing to be restricted, for a copy in a portable form, and you may object to that processing. Write to the address above and we will answer within one month. For your cards themselves you do not need us at all: Settings › Delete all decks and cards erases them from the phone and from your iCloud database at once, and Export gives you a copy.
Complaints. If you think we have handled your data badly, you may lodge a complaint with the data protection authority of the EU or EEA country where you live or work, or with the Information Commissioner's Office in the United Kingdom.
We transfer nothing, because we receive nothing. If you write to us, your email reaches a mailbox we hold in Vietnam. Everything else — the App Store, iCloud, Apple Intelligence — is operated by Apple under Apple's own privacy policy and Apple's own transfer safeguards, not ours.
If this policy changes, the new version is posted here with a new effective date. Questions: zenDesign219@gmail.com.
