Privacy Policy

1. Who We Are

Gamut is developed and published by Jamie Newman ("we", "us", "our"). If you have any questions about this policy, contact us at contact@jamie-newman.com.

2. Data We Collect

Your palettes and colours

• Palette names, ordering, and tags
• Captured and entered colours — their components, colour space, names, and notes
• Capture metadata (e.g. whether a colour came from the camera, a photo, or manual entry)
• App preferences (appearance, colour-space preference)

This data lives entirely on your device using SwiftData. On Pro, it syncs through your private CloudKit database on your own Apple ID. We — the developers — cannot access it under any circumstances.

Camera and photos

Gamut uses the camera solely to sample colour in real time. Camera frames are processed on your device to read a colour value; no photo or video is recorded, stored, or transmitted. When you sample from your photo library, the image is read on-device through the system photo picker to extract the pixel colour you choose — the photo itself never leaves your device and Gamut requests no photo-library permission.

Subscription data

• Subscription and entitlement status, managed by RevenueCat
• A pseudonymous device ID generated by RevenueCat, not linked to your name or Apple ID
• We do not store or process payment card details — all payments are handled by the Apple App Store

Analytics

Gamut uses PostHog, hosted in the EU, for privacy-conscious product analytics — anonymised, aggregate signals about how features are used (for example, which export format was tapped) that help us decide what to improve. This data is not linked to your identity, and your palettes, captured colours, camera frames, and photos are never sent to analytics. There are no advertising or social-tracking SDKs in Gamut. You can turn analytics off at any time in Settings, and Gamut honours Apple's App Tracking Transparency and "Allow Apps to Request to Track" setting.

Apple also provides aggregate, anonymised install and retention metrics at the OS level (not via any Gamut code). You can control this in iPhone Settings → Privacy & Security → Analytics & Improvements → Share App Analytics.

3. How We Use Your Data

• To provide the core experience — capturing, storing, organising, checking, and exporting your colours on device
• To sync your palettes across your own devices via your private iCloud account (Pro only)
• To manage your subscription and restore purchases via RevenueCat
• To power the home-screen palette widget (the widget reads your local palette data; nothing leaves the device)
• To understand, in aggregate and anonymously, which features are used — so we can improve the app (opt-out available)

4. Data Storage & Security

All your palettes and colours are stored locally on your device using SwiftData. Gamut works fully offline without any account.

Pro sync uses Apple's CloudKit service on your own private iCloud database. Data is transmitted over TLS and stored in your Apple-managed iCloud container. The developer has no access to this data — only you, via your Apple ID, do.

Gamut has no backend server for your colour data. There is no Gamut database, no Gamut cloud, and no infrastructure that holds your palettes other than your own devices and your own iCloud account.

5. Third-Party Services

Gamut uses the following third-party services:

• Apple iCloud / CloudKit — private sync across your own devices (Pro only). Governed by Apple's privacy policy.
• Apple StoreKit — in-app purchase processing. Governed by Apple's privacy policy.
• RevenueCat — subscription and purchase management. RevenueCat stores a pseudonymous device ID and your subscription status. See RevenueCat's Privacy Policy for details.
• PostHog (EU) — anonymised, EU-hosted product analytics. See PostHog's Privacy Policy for details.

We do not use advertising networks, social SDKs, or any other third-party services beyond those listed above.

6. Data Sharing

We do not sell, rent, or share your personal data with third parties for marketing or any other purpose. Your palette names, captured colours, and notes are never shared — they live on your device and, for Pro users, in your private CloudKit database. The only data shared with the processors above is the minimum each needs to do its job (subscription management, and anonymised analytics).

7. Notifications

Gamut does not rely on push notifications for its core experience and never sends marketing notifications. Any notification Gamut sends is a local notification generated on your device. Gamut never sends push notifications about your colour data from a server.

8. Your Rights & Data Deletion

• Delete individual swatches or entire palettes at any time from within the app.
• Export a full library archive at any time — data portability is never gated.
• Uninstalling Gamut removes all locally stored data from that device.
• To remove iCloud data globally, go to iPhone Settings → Apple ID → iCloud → Manage Account Storage → Gamut and delete the data there.
• Turn off analytics at any time in Settings.
• To request any data RevenueCat holds about you (subscription status, pseudonymous ID), contact us at the address below and we will facilitate the request.

If you are in the EEA or UK and have questions about your rights under GDPR, or are a California resident with questions about CCPA, contact us at the address below. We will respond within 30 days.

9. Children's Privacy

Gamut is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided information through the app, please contact us so we can address it.

10. Changes to This Policy

We may update this policy from time to time. Changes will be posted on this page with an updated effective date. Continued use of the app after changes constitutes acceptance of the updated policy.
