Privacy Policy
Last updated: November 2026.
Processed on your iPhone, never uploaded
Payslips, receipts and other documents you file are processed entirely on your iPhone. No ClearSlip server ever receives them. This includes receipt reading with Apple Intelligence, which uses Apple's on-device model only — it doesn't use Apple's Private Cloud Compute, and simply doesn't appear on iPhones that can't run it.
Data stored, and where it lives
- Payslip data extracted from what you add — stored locally on your iPhone only
- Expense records and receipt photos — stored locally on your iPhone only
- CPD and study budget entries — stored locally on your iPhone only
- Documents you file (payslips, receipts, study leave forms and similar) — stored in a folder you choose: iCloud Drive, Dropbox or OneDrive
- Backups — stored in that same folder of your choosing, so they survive the app being deleted
- Your profile and settings — stored locally on your iPhone only
The one network request ClearSlip makes
ClearSlip fetches published pay scale and tax data from clearslip.vercel.app/api/pay-scales. This request sends your nation (England, Wales or Scotland), the tax year, and the app version — nothing else, and no payslip or personal data. As with any web request, the host (Vercel) sees your device's IP address and may keep standard request logs.
Data we never collect
- Your name, email, NHS number, or any other personally identifiable information
- Location data
- Usage analytics or advertising identifiers
- Anything about your finances beyond what you explicitly enter or add
There's no account, no analytics SDK, no advertising SDK, and no third-party SDK receives your data.
Purchases
ClearSlip Pro purchases are handled entirely by Apple through StoreKit. ClearSlip never sees your payment details. Because there's no ClearSlip account, purchases are restored through your Apple Account.
Crash reports
Crash reports reach us only through Apple, and only if you've chosen to share analytics with developers in your iPhone's Settings.
Parse reports
If a payslip doesn't read correctly, you can choose to send a redacted parse report. Names, numbers, addresses and your trust's name are removed first, you see the report before it sends, and it goes through your own email app to clearslip@proton.me — never automatically.
Third parties
- Vercel — hosts the pay scale data endpoint described above. Sees no personal or payslip data, only standard web request logs. See Vercel's privacy policy.
- Apple — handles purchases through StoreKit, and iCloud if that's the folder you choose for documents and backup. See Apple's privacy policy.
- Dropbox or OneDrive — only if you choose one of these as your document folder instead of iCloud Drive. That storage is your own account, governed by that provider's own terms.
We use no advertising networks and no data brokers.
Deleting the app
Deleting ClearSlip removes everything stored on your iPhone. Backups and filed documents in your own chosen folder remain until you delete them yourself.
Over-the-air updates
These are disabled, so the app makes no update-check request at launch.
Your rights under UK GDPR
Because we hold no personal data on our servers, most GDPR rights — access, deletion, portability — are exercised directly on your device: delete the app, or use "Delete all data" in Settings. For any other questions, contact us below.
Who we are
ClearSlip doesn't receive your payslip, receipt or expense data. The only personal data we receive is what you choose to send us, such as support emails and parse reports, and standard server logs for the pay scale request. This is handled by Kiely App Development Ltd, Leeds, UK.
