TintBook keeps your work on your phone. There is no account and no advertising. Client names, notes and color formulas stay on your device — we never receive them and cannot see them. From version 1.0.1 the app also sends anonymous usage counts — which screens are used and how often, once a day — to our own server, so we can see what gets in the way and fix it. No identifiers, no third parties, and you can switch it off in Settings.
Everything TintBook creates is written to its own storage on your iPhone: clients, visits, zone formulas, process notes and optional backups you export. None of that content is transmitted to us.
TintBook Pro is an auto-renewing subscription sold through Apple's In-App Purchase system. Apple processes the payment and tells the app whether a subscription is active. We never see your payment details, and we do not receive your name, email or Apple Account information. See Apple's privacy policy for how Apple handles purchase data.
If you share a formula as text or export a JSON backup, iOS hands the content to whichever app or service you choose. From that point the file is governed by that service's terms. We are not involved in the transfer and receive no copy.
From version 1.0.1 the app sends a small daily batch of counters to a server we run ourselves: how often a screen was opened, whether a visit was saved, and whether the subscription screen was reached — grouped only by how long ago the app was installed. There are no identifiers of any kind (no account, no advertising ID, no device ID), no client names and no formulas, and no third-party analytics service. We use it only to see which parts of the app get in the way. Turn it off any time in Settings; nothing is sent while it is off.
TintBook does not use tracking SDKs, advertising identifiers or any third-party analytics service; the only usage data is the anonymous counts described above. Local preferences (for example free-tier bookkeeping and review prompts) use on-device storage only.
TintBook is not directed at children under 13.
If this policy changes, we will update the date above. Continued use of the app after an update means you accept the revised policy.
