  • We process your information to operate the App, provide AI features, improve reliability, and keep the App safe.
  • We use third-party service providers, including Cloudflare (hosting/storage), OpenAI and Google (Gemini) (AI processing), and PostHog (analytics).
  • If you delete your account, we delete your account data and images within 90 days, subject to limited exceptions (e.g., legal obligations and security).

  1. 1.Provide and operate the App (account creation, authentication, storage, sharing spaces).
  2. 2.Provide AI editing features and generate outputs based on your selected style.
  3. 3.Maintain security and prevent abuse (detecting fraud, enforcing rules, protecting infrastructure).

  5. 5.Communicate with you (support replies, important notices, policy updates).
  6. 6.Comply with legal obligations (responding to lawful requests, enforcing our rights).

4Legal bases for processing (EEA/UK)

If you are in the European Economic Area (EEA), UK, or similar jurisdictions, we process personal data under these legal bases:

  • Contract: to provide the App and its features to you.
  • Legitimate interests: to secure, maintain, and improve the App (e.g., preventing abuse, analytics, reliability).
  • Consent: where required for certain analytics or tracking configurations or other optional processing.
  • Legal obligation: to comply with laws and lawful requests.

5How we share information

5.1 Service providers (processors)

We use vendors that process data on our behalf, including:

  • Cloudflare (hosting, content delivery, storage, security) — used to store and deliver App content (including images).
  • OpenAI and Google (Gemini) (AI processing) — used to process images you submit for AI edits and return outputs.
  • PostHog (analytics) — used to understand usage patterns and improve the App.

These providers are permitted to process personal data only to perform services for us and must protect it.

5.2 Sharing with other users

If you join a space or share content in a space, other invited users can view and (depending on features) download or share that content.

5.3 Legal and safety

We may share information if we believe it is reasonably necessary to:

  • comply with law, regulation, legal process, or government request;
  • enforce these policies and our Terms;
  • protect the rights, property, and safety of users, the public, or the Provider.

If the App is transferred (e.g., sale of assets), data may be transferred as part of that transaction. We will provide notice where required.

6International data transfers

We are based in Germany, and our service providers may process data in other countries.

If you are in the EEA/UK and your data is transferred outside these areas, we use appropriate safeguards where required (for example, Standard Contractual Clauses and/or other lawful transfer mechanisms).

  • Logs: Operational/security logs may be retained for a limited period to maintain and protect the service.

8Security

We use reasonable technical and organizational measures to help protect your information. However, no method of transmission or storage is 100% secure.
