Privacy notice (KVKK)
Last updated 14 November 2026
This English translation is provided for information only. The Turkish version is legally binding and prevails in case of any discrepancy.
Sealingo processes your account, contact and billing information to provide the service, issue invoices, ensure security and fulfill its legal obligations. The Turkish identification number (for individual customers and for sole proprietorships that use it as their tax number) is processed only for invoicing and tax obligations. Sealingo does not use this information for marketing and does not sell it. For persons named in the documents commercial customers upload for translation, the data controller is the relevant customer. For consumers who open an individual account for personal use, however, Sealingo is also the data controller for the uploaded documents, translations and Seal conversations (Clause 8); these documents are processed for translation, are not used to train models and are deleted within the chosen period. In sworn and notarized delivery, Sealingo processes delivery and pickup information (name, telephone number, address) only for delivery and transfers it to the partner agency handling the job and to the courier. This information is deleted 90 days after the order is concluded.
This summary is for information only; the text below is what applies.
1. Data controller and scope of this notice

1.2. This notice covers the following persons:

1.3. For persons whose personal data is contained in the documents commercial customers (business customers and persons who create an individual account for professional use) upload for translation (the customer's own clients and other persons named in the documents), the data controller is the business or individual customer that uploads the document. This clause does not apply to consumer customers; Sealingo is the data controller for their documents and content (Clause 8). The same applies to the terms the customer enters in the account glossary; no personal data is entered in the account glossary. Information in the folders the customer creates (folder name, note, folder glossary) may contain names of persons and companies; the customer is the data controller for this as well. Sealingo processes this data on the customer's instructions as data processor (Data Processing Agreement). Informing these persons is the obligation of the relevant customer. Requests received by Sealingo in this context are forwarded to the relevant customer. If the customer chooses sworn or notarized delivery, these documents are transferred to the partner agency handling the job and, in notarized delivery, submitted to a notary; the customer is the data controller for these as well.
