Privacy policy
Short and in plain language — what data we process, why, how long we keep it, and who we share it with.
Operator and data controller
Čočka (cocka.cloud) is operated by Techtribe s.r.o., a Czech limited company, IČO (Business ID) 23804424, VAT ID CZ23804424, registered at Na Čečeličce 425/4, Smíchov, 150 00 Praha 5, Czech Republic — the data controller for your personal data under GDPR.
What data we process
- Photos of receipts/documents you send us (by email, Telegram, or the web upload).
- Data extracted from them by OCR and AI processing — supplier, buyer, amounts, VAT, date, document numbers, etc.
- Supplier/buyer details verified against the Czech ARES public registry (name, business ID, VAT ID, registered address).
- Account details — name, email, phone, your company name and business ID.
- Billing and usage data — number of documents processed, payment history.
Why we process this data
Solely to provide the service itself: OCR and AI extraction of a receipt's data, supplier verification via ARES, generating the ISDOC file, and making it available in your receipt gallery. Billing data is processed to invoice you for the service.
How long we retain data
We keep documents and the data extracted from them for as long as your account is active — we don't currently have automatic deletion after a fixed period. You can delete an individual document yourself in the app; to delete your whole account or request a data export, contact us at the email below.
Who we share data with
We verify supplier details against the public ARES registry (Czech Ministry of Finance) — this is a read-only lookup of publicly available data, not a transmission of your data to ARES.
OCR and AI extraction run on our own infrastructure — a GPU server we operate ourselves. Your receipt's photo or text is never sent to any external AI/cloud service (e.g. OpenAI or similar) — that's a deliberate technical and privacy difference from typical SaaS OCR tools.
Documents and files (photos, ISDOC) are stored in an object store (MinIO/S3-compatible) that we also run on our own infrastructure. We do not share data with any other third parties for marketing or analytics purposes.
Your rights
You have the right to access, correct, or delete your personal data. You can delete or correct individual documents yourself in the app; for a full data export, full account deletion, or other GDPR-related questions, contact the email on your account, or Techtribe s.r.o. directly. There's currently no self-serve button in the app for these requests — we handle them manually.

Questions about data protection go to the contact email on your account, or directly to Techtribe s.r.o. See also our terms of use.
