2. Purpose
We process the submitted information only to verify product installation, provide after-sales support, investigate product quality issues and protect the service from misuse.
3. Information processed
Required: SUMATE internal product number, installation date and a product/installation photo.
Optional: repair shop business or trade name. Do not enter a person's name, telephone number or other contact details.
We also retain the selected language, submission time, consent time and policy version, record identifier, and limited security logs necessary to operate the service.
4. Images and prohibited information
Do not upload license plates, faces, identity documents, phone numbers, addresses or any other personal data. Before upload, supported images are re-encoded in your browser to remove embedded location and device metadata. This process does not detect or blur visible faces, plates or text. Our staff may delete a non-compliant image without notice.
5. Processing and storage
The information is collected through our support website, transmitted securely and accessed only by authorised support staff. Operations may include collection, recording, organisation, storage, review, use for the stated purpose and deletion.
6. Retention
We keep a support submission only as long as necessary for the stated purpose and normally for no more than 180 days after the service case is resolved. We then delete or anonymise it unless a longer period is required to establish, exercise or defend legal claims.
7. Your choices and rights
You may request access, correction, restriction or deletion, object to processing where applicable, or withdraw consent by emailing jay@sumaterus.com. Withdrawal does not affect processing already carried out before it was received. If the required information is not provided, we may be unable to handle the support request.
8. Changes
We may update this policy when the service or applicable requirements change. The version accepted with each submission is recorded.
