Gamut

Privacy Policy

Last updated: 8 November 2026  ·  Applies to Gamut 1.1 and later

The short version: Gamut stores your palettes and colours on your device. Pro users sync through their own private iCloud account. There is no Gamut server. From version 1.3.0, the free version shows banner ads from Google AdMob; Gamut Pro, and any install first downloaded before 1.3.0, has no ads. Otherwise, the only data that leaves your device is anonymised, EU-hosted product analytics (which you can opt out of) and the purchase information Apple and RevenueCat need to manage your Pro purchase. Your palettes and captured colours are never sold, shared, or used for anything but running the app.

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

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.

Colour generation and contrast correction

Gamut 1.1 can derive new colours from one of yours - a harmony or a tonal ramp - and can suggest the nearest colour that passes a failing contrast check. Both are deterministic colour mathematics computed entirely on your device. There is no AI service, no remote model, and no network request of any kind: your colours are not sent anywhere to be processed, and the results are only stored if you choose to keep them, at which point they are ordinary swatches in your own palette.

Purchase data

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. Analytics data is not used for advertising, and there are no social-tracking SDKs in Gamut. You can turn analytics off at any time in Settings.

Advertising (free version, from 1.3.0)

From version 1.3.0, the free version of Gamut shows one banner ad on each screen except Capture, served by Google AdMob. There are no ads, and the ad software never starts, for:

On those devices no consent form or tracking prompt appears. Where ads are shown, Google's Mobile Ads SDK collects data from your device to serve and measure them: a device identifier (including Apple's advertising identifier, if you allow tracking), approximate location derived from your IP address, the ads you have seen and your interactions with them, and app performance and crash information. Your palettes, captured colours, camera frames, and photos are never shared with Google or used for advertising.

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

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:

We do not use social SDKs or any other third-party services beyond those listed above. Google AdMob is the only advertising network in Gamut.

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 (purchase management, and anonymised analytics). In the free version, from 1.3.0, the Google Mobile Ads SDK sends Google the advertising data described in section 2, and Google may use it to serve and measure ads, as its own policies describe. That data never includes your palettes, colours, notes, camera frames, or photos.

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

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.
