Privacy Policy
Last updated: May 15, 2026
Theme Studio (the "Service") is operated from themestudio.co and as a companion iOS app on the App Store. This policy explains what data the Service processes and how.
Short version: we don't collect or sell personal information. The web editor runs entirely in your browser. The iOS app stores your themes on your device.
1. What we collect
1.1 Web editor (themestudio.co)
Everything you create in the web editor is stored locally in your browser using IndexedDB and localStorage. It never reaches our servers.
| Data | Where | Purpose |
|---|---|---|
| Themes you create | Browser IndexedDB | So your work survives a page reload. |
| Uploaded images (wallpaper, icon bg, widget bg) | Browser IndexedDB (as Blobs) | Bundled into your .tstheme export. |
| Notes | Browser localStorage | So you have a scratchpad while you work. |
| UI preferences (column count, expanded packs) | Browser localStorage | To remember your last view. |
Wallpapers and icon images you browse are loaded from our CDN at
natewren.com. Standard HTTP request logs (IP address,
user-agent, referrer, requested URL) are retained by our CDN
provider, Cloudflare, for security and abuse mitigation. We do not
attach those logs to any user identity.
1.2 iOS app
The Theme Studio iOS app reads its bundled themes from the app's own resources and stores your own creations on your device only. We do not transmit your themes, wallpapers, or device identifiers to any server we control.
2. Accounts & subscriptions
The web editor does not currently require an account.
In a future release, you may sign in with Sign in with Apple to unlock features that require a subscription. When that ships, the following will apply:
- Sign in with Apple gives us a per-app user identifier (a random string assigned by Apple) and, if you choose to share it, your name and a forwarding email address. We use this only to associate your subscription state with your session.
- Subscription management is handled by Apple (App Store) or Google (Play Store) and a third-party billing platform (RevenueCat). We never see your payment card.
- Cross-platform sync of subscription status between iOS, the web app, and a future Android app uses your Sign in with Apple identifier as the link. Nothing else syncs.
3. Analytics
themestudio.co uses Cloudflare Web Analytics for aggregate traffic reporting. It does not use cookies, does not store an identifier tied to your browser, and does not see any personally identifiable information. We use it to know which pages people visit.
The iOS app does not include any third-party analytics.
4. Cookies and similar technologies
themestudio.co does not set any cookies. It uses your browser's local storage and IndexedDB to remember your themes; these never leave your device.
5. Children
Theme Studio is not directed at children under the age of 13 (or under 16 in the EU/UK). We do not knowingly collect data from children. If you believe a child has provided data, contact us and we'll remove it.
6. Your rights
Because we hold no personal data on our servers, there is generally nothing for us to access, correct, or delete on your behalf. To delete the data the web editor stores in your browser, use the Delete My Data page or clear site data for themestudio.co in your browser's settings.
Once accounts launch, you'll be able to request deletion of any stored account information by emailing hello@themestudio.co. We'll respond within 30 days.
7. Data retention
Web-editor data is retained on your device for as long as you choose. Cloudflare's standard CDN logs are retained for a short period per their policy and are not linked to any user identity.
8. International users
Theme Studio is operated from the United States. Our CDN serves content from edge locations worldwide. If you are visiting from outside the United States, your interaction with our site involves transferring information across borders.
9. Changes to this policy
We may update this policy when the product changes (e.g. when we add accounts or subscriptions). The "Last updated" date at the top will change to reflect that. Material changes will be highlighted on the home page.
