Privacy Policy
SubSlot for iOS · Last updated 4 August 2026
SubSlot does not collect your data. There is no account, no bank login, no email access, and no analytics. Everything you track is stored on your iPhone, and optionally in your own private iCloud. We never receive a copy of it.
1. Who we are
SubSlot is developed by Makinon ("we", "us"), the data controller for the little personal data this policy describes. It covers the SubSlot iOS app, including its widget and its Mail share extension, and this website. Contact: support@subslot.app.
2. What is stored on your device
The following is written to local storage on your iPhone (Apple's SwiftData framework) and to an App Group shared with the widget and share extension. It stays there:
- The subscriptions you track — name, amount, currency, billing cycle, renewal date, category, notes and trial status.
- Your settings — base currency, reminder time, and whether reminders are on.
- A snapshot of exchange rates, so totals still work offline.
- Your answers in the keep-or-cancel review.
Your spending totals, trends and savings figures are calculated on your device, from that data, every time you look at them. Nothing is computed on a server.
3. What leaves your device
One thing, and it contains nothing personal:
| Request | Sent to | What it contains |
|---|---|---|
| Exchange rates, at most twice a day | api.frankfurter.dev (European Central Bank reference rates) | Only currency codes, e.g. base=USD&symbols=EUR,GBP,SGD. No subscription, amount, device or user information is included. |
That is the complete list of network requests the app makes on its own behalf.
4. What explicitly does not leave your device
- Receipt screenshots. You choose the images in Apple's photo picker, which hands the app only what you picked — the app never gets access to your photo library. Text recognition then runs on-device using Apple's Vision framework. Images are read and discarded; none is uploaded.
- Receipts you share or paste. Parsed on-device by the app and the share extension.
- Your subscriptions and amounts. We operate no server that could store them.
5. iCloud sync
If you are signed in to iCloud, your subscriptions sync between your own devices through Apple's CloudKit, in your private database inside your own iCloud account. That storage is governed by Apple's Privacy Policy and counts against your iCloud quota. We have no access to it — we cannot read, export or delete it. Turn it off by signing out of iCloud or disabling iCloud Drive for the app; the app then keeps working on-device only, and Settings shows which mode is live.
6. Purchases
SubSlot Pro is sold through Apple's In-App Purchase. Apple handles the payment and tells the app only whether an entitlement is active. We never see your name, email, card or billing address. We use no receipt server and no third-party purchase analytics.
7. Notifications
Renewal and trial reminders are local notifications scheduled on your device. Nothing is sent through a push server, so no notification content passes through us.
8. Tracking and advertising
None. SubSlot contains no advertising, no analytics SDK, no crash-reporting SDK and no tracking of any kind, so it does not ask for App Tracking Transparency permission. We do not sell or share data, because we do not have any.
9. Links out of the app
Some subscriptions in the app's catalogue have a "cancel" link, and the paywall links to Apple's subscription settings. Opening one leaves SubSlot and hands you to that company's own site or to Apple, where their privacy policy applies, not ours. We are not affiliated with the services listed in the catalogue and we send them nothing about you.
10. What Apple tells us
Two things reach us through Apple rather than through the app, and neither identifies you:
- App Store reports. Aggregate downloads, sales and refunds, and — only if you turned on Share With App Developers in iPhone Settings → Privacy & Security → Analytics & Improvements — aggregated usage statistics and crash reports. Apple aggregates these before we see them.
- Ratings and reviews you choose to write on the App Store, under whatever nickname you use there.
11. If you email us
If you write to support, we hold your email address, your message and anything you attach — for as long as it takes to answer you and a reasonable period after, in case you write again. We use it to reply and nothing else. The legal basis is our legitimate interest in answering support requests. Ask us to delete the thread and we will.
12. Children
The app is not directed at children under 13 and collects no data from anyone.
13. Your rights
Rights such as access, correction, export and deletion (GDPR, UK GDPR, CCPA and similar) normally require a request to the developer. Here they are immediate and in your hands: your data is on your device. Export it to CSV from Settings, edit or delete any entry in the app, and delete all of it by deleting the app (and, for synced copies, by removing the app's data from iCloud in Settings → your name → iCloud). We hold no copy to return or erase. For the one exception — a support email you sent us — write to support@subslot.app and we will act on it. If you think we have handled something badly, you can also complain to your national data protection authority.
14. Changes
If this policy changes, the date at the top changes with it, and the previous versions remain in the app's public repository history.
