Privacy Policy

Last updated: October 5, 2026

1. Introduction

Welcome to Diceify ("we," "our," or "us"). We respect your privacy and are committed to protecting your personal data. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our dice mosaic art generator at diceify.art and in the Diceify iOS app (together, the "Service").

2. Information We Collect

2.1 Information from Sign-In

You can sign in with Google or with Apple. We receive and store:

  • Google: your email address, your name and your profile picture
  • Apple: your email address (a private relay address if you choose Hide My Email) and the name you choose to share

We use this information to create and manage your account, personalize your experience, and communicate with you about your account.

2.2 Project Data

When you create dice mosaic projects, we store:

  • Images you upload for conversion
  • Project settings (grid size, color mode, contrast, etc.)
  • Crop and rotation parameters
  • Build progress data

Your images are converted into dice patterns on your device, in your browser or in the iOS app. Project data is stored only when you are signed in: it is saved to your account (database and file storage provided by Supabase) so you can continue your work across devices.

Without an account: if you use the editor without signing in, your draft stays on your device. On the website, the project settings are kept in your browser's local storage and the photo in its IndexedDB database; in the iOS app, both are kept in the app's own storage. Nothing is uploaded to us until you sign in and save the project to your account.

Photos in the iOS app: you choose a photo with the system photo picker, which gives the app only the photo you pick, or take one with the camera, which asks for your permission first.

Share links: when you create a share link, the dice-pattern card for that share is public to anyone who has the link. It contains the dice pattern, not your original photo.

2.3 Payment Information

If you purchase a subscription or a Creator Pass on the website, payment processing is handled securely by Stripe. We do not store your credit card details. We store a Stripe customer ID and the status and dates of your purchase or subscription to manage your access.

Subscriptions bought in the iOS app are processed by Apple and charged to your Apple ID; we never see your payment details. RevenueCat, the service we use to verify App Store purchases, receives your account ID and the purchase receipt, and we store the product, its expiry date and whether it renews.

2.4 Analytics and Error Reporting

We use the following services to understand how people use Diceify and to find bugs:

  • Google Analytics 4: pages visited, the steps of the editor you use, and general usage patterns.
  • PostHog: product analytics (the same kind of events) and session replay, which records clicks, scrolling and page changes for some visits. Photos you upload and the dice previews generated from them are masked and never appear in a recording. The iOS app sends PostHog the same product events, without session replay, and does not use Google Analytics.
  • Cloudflare: hosts the site and serves it through its network; its Web Analytics beacon measures page loads.
  • Sentry: receives error reports from your browser when something in the Service fails.

When you are signed in, analytics events and error reports are linked to your account ID (not your name or email) so that we can understand and fix problems for a specific account. Visitors who are not signed in are not identified.

3. How We Use Your Information

We use the information we collect to:

  • Provide, operate, and maintain our Service
  • Create and manage your user account
  • Save and sync your projects across devices
  • Process payments
  • Send you service-related communications
  • Improve and optimize our Service
  • Detect and prevent fraud or abuse

4. Data Storage and Security

Your account, projects and uploaded images are stored by Supabase (authentication, a PostgreSQL database and file storage), with access rules that restrict each user's data to that user. The website itself is served by Cloudflare. All data transmission is encrypted using HTTPS. We implement appropriate technical and organizational measures to protect your personal data against unauthorized access, alteration, disclosure, or destruction.

5. Data Sharing

We do not sell your personal data. We may share your information with:

  • Service Providers: Third-party services that process data on our behalf to operate the Service: Supabase (authentication, database and file storage for saved projects), Stripe (payments on the website), Apple (Sign in with Apple and App Store payments), RevenueCat (App Store purchase verification), Cloudflare (hosting, content delivery and web analytics), Google Analytics 4 and PostHog (analytics and session replay), and Sentry (error reporting)
  • Legal Requirements: When required by law or to protect our rights

6. Data Retention

We retain your account data and projects for as long as your account exists. You can delete your account at any time from the account page on the website or in the app: this immediately deletes your profile, projects, uploaded images and share cards from our systems and cancels an active subscription bought on the website. A subscription bought in the iOS app is billed by Apple and keeps renewing until you cancel it in your Apple ID's subscription settings. Payment records are kept by Stripe, Apple and RevenueCat as required for accounting and legal purposes, and analytics and error data are retained by the services listed in Section 2.4 according to their own retention settings.

7. Your Rights

You have the right to:

  • Access the personal data we hold about you
  • Request correction of inaccurate data
  • Request deletion of your data
  • Export your project data
  • Withdraw consent for data processing

To exercise these rights, please contact us at the email address below.

8. Cookies

We use your browser's local storage to maintain your sign-in session and, for anonymous visitors, your draft. The analytics services in Section 2.4 set their own cookies or local storage to recognize returning visitors. You can control cookies and site data through your browser preferences. In the iOS app, your sign-in session is kept in the device's Keychain and your draft in the app's own storage; deleting the app removes the draft.

9. Children's Privacy

Our Service is not intended for children under 13 years of age. We do not knowingly collect personal data from children under 13. If you believe we have collected data from a child under 13, please contact us immediately.

10. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date. We encourage you to review this Privacy Policy periodically.
