This website and the TAIL Sampler application are operated by Solid Grid Systems GmbH, Bundesallee 187, 10717 Berlin, Germany.
When you create an account or purchase a license, we collect: your email address, your license key, and basic account data required for authentication. The installed native applications (iOS, Android, and the desktop plugin) do not collect analytics, tracking data, or usage telemetry. On our public website — including the free browser edition of the sampler you can try without installing — we use privacy-friendly, self-hosted analytics to understand aggregate traffic and which features get used. This covers page visits and a small set of anonymous in-app actions (such as saving a project or adding a sample). It does not use cookies, does not track individuals across sites, and does not collect personally identifiable information. All data is stored on our own servers in Europe.
We use your account data solely to provide the Service: authenticating your account, validating your license, and communicating with you about your purchase or account. Website analytics data is used only in aggregate to understand traffic patterns and improve our public website; it is never used to identify or profile individual visitors.
Payments are processed by Paddle.com (Paddle Payments Ltd), who acts as the Merchant of Record. Paddle collects and processes your payment information directly. We do not store your credit card or payment details. Please refer to Paddle's privacy policy for details on how they handle your data.
Account authentication is handled on our own infrastructure in Europe. Your email and hashed password are stored securely; we never have access to your plain-text password, and your authentication data is never sent to any third party.
Your data is stored on secure servers. We retain your account and license data for as long as your account is active. You may request deletion of your data at any time by contacting us.
We do not sell, trade, or share your personal data with third parties, except as required to provide the Service (Paddle for payments). Both our authentication and our website analytics are self-hosted on our own infrastructure in Europe, so that data is never shared with any third party.
If you are located in the EU, you have the right to access, correct, or delete your personal data. You also have the right to data portability and the right to lodge a complaint with a supervisory authority. To exercise your rights, contact us at hi@solidgridsystems.com.
This website does not use cookies. Authentication sessions are handled using token-based storage in your browser, and our analytics is cookieless. We do not use tracking or advertising cookies.
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date.
