PRIVACY POLICY

Last updated September 8, 2026

ByteSurf OÜ ("Partlake", "we", "us") operates Partlake, a semiconductor product data platform. This policy explains how we handle personal data when you visit partlake.com, use the Partlake platform, or contact us.

For most of the personal data described in this policy we act as a controller – we decide why and how it is processed. This includes account records, sign-in and API logs, security monitoring data, support correspondence, and billing contact details.

Where a business customer supplies us with a list of work email addresses so we can provision access for its people, we act as a processor for that list, on the customer's instructions and under our agreement with them. Once an account exists, we are the controller of the account record and of the data generated through use of the platform.

Information you provide to us. When you contact us or request information about Partlake, we collect the name, work email address, and company name you give us, together with the content of your message.

Information we receive from your identity provider. Partlake accounts are created through single sign-on. When you sign in using your organisation's identity provider, e.g. Microsoft, we receive your name, work email address, and an account identifier. We do not create or store passwords and have no access to your credentials at your identity provider.

Information provided by your organisation. Where your employer subscribes to Partlake, it may provide us with the work email addresses of the people who should be given access, so that we can provision their accounts.

Billing information. Where your organisation gives us a named billing contact, we process that person's name, work email address, and job title for invoicing and account administration.

Information collected automatically. When you use Partlake we log technical data including IP address, browser and device type, pages and API endpoints accessed, and timestamps. We use this for security, abuse prevention, diagnostics, and to understand how the platform is used.

We use only cookies that are strictly necessary to operate partlake.com and the Partlake platform, such as keeping you signed in after authentication.

We do not use analytics, advertising, or tracking cookies, and we do not permit third parties to set cookies through on our site. Where we analyse how the platform is used, we do so from our own server-side logs rather than by tracking you across sites or devices.

We process personal data for the following purposes:

  • To provide the platform. Creating and administering accounts, authenticating users through your organisation's identity provider, and making Partlake's data and API available to authorised users.
  • To administer the customer relationship. Negotiating and performing subscription agreements, invoicing, and handling support requests.
  • To communicate with you. Responding to enquiries and sending service and administrative messages about your account, the platform, or changes to our terms.
  • To keep the platform secure. Monitoring for unauthorised access, abuse of the API, and misuse of licensed data, and investigating incidents.
  • To maintain and improve the platform. Diagnosing faults and understanding which features and data are used, so we can develop the service.
  • To comply with legal obligations. Meeting accounting, tax, and record-keeping requirements, and responding to lawful requests from authorities.
  • To establish or defend legal claims. Where necessary to enforce our terms or protect our rights.

We do not sell personal data or share it for advertising.

We use a small number of service providers to operate Partlake, e.g. cloud hosting, business email, and application monitoring. Where they process personal data on our behalf, they do so under data processing terms imposing confidentiality and security obligations. Business customers can request a current list of these providers.

We use a small number of service providers to operate Partlake, e.g. cloud hosting, business email, and application monitoring. They process personal data only on our instructions, under written contracts imposing confidentiality and security obligations. Business customers can request a current list of providers, which is also set out in the data processing agreement where one is in place.

Your organisation's identity provider, e.g. Microsoft, acts independently under its own privacy policy when it authenticates you.

We may also disclose personal data to our professional advisers, where required by law, where necessary to establish or defend legal claims, or in connection with a merger, acquisition, or sale of assets.

We keep personal data for as long as needed for the purposes described above, and afterwards only where required for accounting and tax obligations or to establish or defend legal claims.

Under the GDPR you have the right to request access to your personal data, to have inaccurate data corrected, to have your data erased, to restrict or object to our processing, and to receive your data in a portable form. These rights are subject to conditions and exceptions under applicable law.

To exercise any of these rights, contact us at . If you are unhappy with how we have handled your personal data, you also have the right to complain to a supervisory authority.

We do not sell personal data, share it for targeted advertising, or use it for profiling. If you are a resident of a US state with applicable privacy legislation, you may have rights to access, correct, or delete your personal data. You can exercise these using the contact details above.

Some of our service providers are located outside the European Economic Area. Where that is the case, we rely on the European Commission's standard contractual clauses or an adequacy decision to protect your data.

We may update this policy from time to time. The date at the top shows when it was last changed.
