stacked. — Privacy Policy

stacked.

Last updated: September 17, 2026

This Privacy Policy explains how stacked. (the “App”) collects, uses, shares and protects your information. The App was previously called “Collex”. The App is operated by the developer of stacked. (Kazakhstan) — “we”, “us”.

Short version: we collect only what is needed to run your collections and the social features you choose to use. We do not sell your data, we do not show ads and we do not track you across other apps or websites.

1. Information we collect

Account data. Email address and password (if you register with email), or the identifier and email provided by Sign in with Apple (this can be an Apple private relay address). Passwords are handled by our authentication provider and are never stored in plain text.

Profile data. Username, and optionally your name, bio, avatar photo, date of birth and country. You decide what to fill in.

Your content. Collections and categories, items, photos, descriptions, ratings, tags, wishlist items, purchase date and price (if you add them), cover images and privacy settings.

Social activity. Friends and friend requests, likes, in-app notifications, blocked users and reports you submit.

Usage data. Collector rating and rank, time spent in the App, “last seen” / online status, selected app language, and basic technical information needed to deliver the service (such as IP address in server logs).

Guest mode. If you use the App without an account, your data is stored only on your device. If you later create an account, you can move that data to your account.

2. Device permissions

Camera — to take photos of your items. Only used when you tap the camera button.
Photo Library — to pick photos for items, covers and your avatar, and to save item cards to your gallery. We only access photos you select.

You can change these permissions at any time in iOS Settings.

3. How we use information

to create and secure your account and keep you signed in;
to store, sync and display your collections across your devices;
to show your public profile, collections, leaderboard position and activity to other users — only within the visibility settings you choose;
to power friends, likes, notifications and the activity feed;
to calculate collector rating and ranks;
to moderate content, handle reports and keep the community safe;
to answer your support requests and fix problems.

4. What other users can see

Depending on your profile and collection visibility settings, other users may see your username, name, avatar, bio, country, collector rating and rank, online status, public collections, items and photos, and likes. Private collections and hidden profiles are not shown to others. Your email address and password are never shown to other users.

5. Service providers

We share data only with providers that help us run the App:

Supabase — database, authentication, file storage and realtime updates (hosting of all account data and photos).
Apple — Sign in with Apple and App Store distribution. Apple may share anonymous crash reports with us if you allow it in iOS settings.
Google Translate — texts written in the App (such as item descriptions) may be sent to Google to show an automatic translation into your app language. No account data is sent with them.

Your data may be processed on servers located outside your country. We do not sell or rent personal data and we do not use third-party advertising or analytics SDKs.

6. Reports and moderation

When you report a user or content, the report (reason, your comment, and the reported username, email and collection) is sent to our moderators. Reports are reviewed, and we aim to act within 24 hours. We may keep reports and moderation records as long as needed to protect users and prevent abuse.

7. Data retention and deletion

We keep your data while your account exists. You can delete your account at any time in Settings → Delete account. This removes your profile, collections, photos and related data from our systems. Residual copies in backups may remain for a limited period before being overwritten. Data stored in guest mode stays on your device until you delete the App.

8. Security

Data is transmitted over encrypted connections (HTTPS), sign-in tokens are stored in the iOS Keychain, and access to data on the server is restricted by account. No system is 100% secure, so please use a strong, unique password.

9. Your rights

You can view and edit your profile and content in the App, change visibility settings, and delete your account. You may also ask us to access, correct, export or delete your personal data, or object to its processing, by writing to jamesolsly@gmail.com. Depending on where you live (for example the EU, UK, California or Kazakhstan), you may have additional rights under local law.

10. Children

The App is not intended for children under 13 (or the minimum age required in your country). We do not knowingly collect personal data from children. If you believe a child has provided us with data, contact us and we will delete it.

11. Changes to this policy

We may update this Privacy Policy. We will change the “Last updated” date and, for significant changes, notify you in the App.
