We do not process special categories of personal data (such as health or biometric data). We do not build marketing profiles and do not use advertising or cross-site tracking cookies. We recommend avoiding people in your product photos.
3. Purposes of processing
- Creating your account, verifying your email address, and handling sign-in and password resets;
- Providing the Service: storing product photos, extracting product attributes from photos with artificial intelligence, generating catalogues and PDFs, previews, share links and QR codes;
- Tracking plans, periods and analysis credits, reviewing upgrade requests and, once a payment provider is integrated, processing payments;
- Sending in-app and push notifications, verification codes and password reset emails;
- Ensuring information security, preventing unauthorised access and abuse, rate limiting, detecting and fixing errors;
- Monitoring usage statistics and service costs to keep the Service reliable and improve it;
- Responding to support requests and communicating with you;
- Complying with legal obligations, responding to requests from competent authorities and protecting our rights in potential disputes.
4. Legal grounds
We process your personal data on the following legal grounds under Article 5 of the KVKK:
- Establishment or performance of a contract (Art. 5/2-c): opening your account, providing the Service, AI analysis, catalogue generation, notifications and plan management.
- Compliance with a legal obligation (Art. 5/2-ç): statutory retention and disclosures to authorities.
- Establishment, exercise or protection of a right (Art. 5/2-e): using records as evidence in a dispute.
- Legitimate interest (Art. 5/2-f): information security, activity logs, error monitoring and aggregated usage statistics, provided this does not harm your fundamental rights and freedoms.
- Explicit consent (Art. 5/1): only where none of the above applies and, for transfers abroad, where the other conditions of Article 9 of the KVKK cannot be relied on — given through the consent box at sign-up. You may withdraw consent at any time; withdrawal does not affect prior processing.
5. Transfers of personal data
We transfer personal data only for the purposes above and only to the extent necessary, to the following recipients:
| Recipient | Data transferred | Purpose | Country |
|---|---|---|---|
| AI service provider: Anthropic, PBC (Claude) | A downsized copy of product photos and the industry attribute list. Your name, email and company details are not sent. | Extracting product attributes from photos | USA |
| Email delivery provider: Resend, Inc. | Email address and the message containing the verification/password reset code | Delivering transactional emails | USA |
| Push notification infrastructure: Expo (650 Industries, Inc.), Apple Inc., Google LLC | Notification token and notification text | Delivering push notifications | USA |

| Competent public authorities and courts | Information requested under applicable law | Legal obligation | Türkiye |
Transfers abroad
Our AI, email and push notification providers are located abroad (USA). These transfers are made under Article 9 of the KVKK by putting in place one of the appropriate safeguards, such as signing the standard contractual clauses announced by the Personal Data Protection Board and notifying them to the Authority, or, where that is not possible, under the statutory exceptions and your explicit consent.
Only the product photo and the attribute list are sent to the AI provider. Under its commercial terms, the provider commits not to use content processed through its API to train its models. Your photos are only read to extract attributes; your product is never altered.
6. How we collect data
Personal data is collected electronically through the mobile app, web pages and email — either entered by you or collected automatically while you use the Service (device and activity logs).
7. Retention periods
| Data | Retention |
|---|---|
| Account and content data (profile, products, photos, catalogues) | For as long as your account is open. When you delete your account, access ends immediately and the data is permanently deleted within 30 days. |
| Deleted products and catalogues | Permanently purged 30 days after deletion. |
| Verification and password reset codes | Valid for 10 minutes; deleted with the account record after use or expiry. |
