01Who We Are

SYNTH is a social platform for AI-generated imagery, operated from Switzerland. This policy explains what personal data we collect, why we collect it, and what rights you have over it.

If you have questions, contact us at: privacy@onsynth.com

VercelHosting and deploymentServer logs, IP addresses

05AI-Generated Content and Ownership

You retain ownership of the prompts you write. You represent that you have the right to upload any content you post to SYNTH.

AI-generated images are produced by third-party models (Midjourney, Flux, Gemini, etc.). We do not claim ownership of content you create using those tools. However, by uploading content to SYNTH you grant us a non-exclusive licence to display, distribute, and reproduce that content within the platform.

When you sell content through the SYNTH Market or Auction, ownership of that specific post transfers to the buyer within the platform. This is a platform-level transfer and does not affect any intellectual property rights related to the underlying AI model.

06Coins and Virtual Economy

SYNTH Coins are a virtual in-platform currency. They have no monetary value, cannot be exchanged for real money, and are not refundable. Coin balances may be adjusted by platform mechanics including Arena outcomes, Market transactions, and system events.

Arena backing involves placing virtual coins on outcomes. This is an entertainment mechanic within the platform and does not constitute gambling or financial speculation.

07Data Retention

We retain your data for as long as your account is active. If you delete your account:

  • Your profile, posts, and activity data are deleted within 30 days
  • Email records are retained for 90 days for legal compliance
  • Aggregated, anonymised analytics may be retained indefinitely

You can request deletion at any time by emailing privacy@onsynth.com.

08Your Rights

Under Swiss nDSG and GDPR (where applicable), you have the right to:

  • Access — request a copy of the data we hold about you
  • Correction — request correction of inaccurate data
  • Deletion — request deletion of your account and data
  • Portability — receive your data in a machine-readable format
  • Objection — object to processing based on legitimate interest
  • Withdraw consent — for newsletter communications, unsubscribe at any time

To exercise any right, email privacy@onsynth.com. We will respond within 30 days.

09Cookies

SYNTH uses essential cookies only — for authentication sessions and security. We do not use tracking or advertising cookies.

10Children

SYNTH is not intended for users under 16 years of age. We do not knowingly collect data from children.

11Changes to This Policy

We will notify registered users by email if we make material changes to this policy. The latest version is always available at onsynth.com/privacy.
