Privacy Policy
AstroGrid is a one-person project. This Privacy Policy explains what data I ("I", "me", "my") collect when you use the Service at velonspace.com, and how that data is handled. I aim to collect as little as possible.
1. Data I do not collect
Account registration is not required to use the Service. For ordinary exploration, search, deep-link sharing, screenshots, and the local scene editor, I do not ask for your name, email, address, phone number, or any other personally identifying information. An optional Google sign-in (described in Section 4) is planned for as early as May 2026 and will only be used by people who choose to enable cloud-saved features.
2. Data stored locally on your device
The Service stores your preferences (such as quality settings, language, and last visited scene) in your browser's local storage and IndexedDB. This data never leaves your device and can be cleared at any time through your browser settings.
3. Analytics
I may use privacy-respecting analytics to understand aggregate usage patterns, including page views, session duration, browser type, and approximate region. These analytics do not identify you individually and respect the "Do Not Track" browser setting.
Specifically, I may use one or more of: Google Analytics 4 (configured with IP anonymization), Cloudflare Web Analytics, and Sentry (for crash reports). Crash reports include technical details such as browser version, error stack traces, and the URL where the error occurred, but do not include personal information.
4. Optional Google sign-in
As early as May 2026, the Service will offer an optional Google sign-in (Google OAuth 2.0) so that people who want to keep personal data — such as custom-created stars or scene-editor sequences — backed up to the cloud and synchronised across devices can opt in. Sign-in is entirely optional: every other feature continues to work without it.
When you choose to sign in, Google passes me only the minimum information needed to identify you: your email address, display name, and profile picture URL. I do not request access to your Gmail, Drive, contacts, or any other Google data. I do not receive or store your Google password. You can revoke this connection at any time from your Google account's Security → Third-party access settings.
If you sign in, the only data linked to your account on my side is the personal content you explicitly create or save through the signed-in features. To delete or export your account data, email me at the address in Section 11 and I will handle the request. Google's own handling of the authentication exchange is governed by Google's Privacy Policy.
5. Payments
Optional support payments are processed by Ko-fi, the platform I use to receive contributions. When you make a payment, Ko-fi (and its underlying payment processors, such as Stripe or PayPal) collects the information necessary to complete the transaction (such as your name, email, and payment details). I receive only a transaction summary; I do not receive or store your payment card details.
Ko-fi's handling of your payment data is governed by their own privacy policy.
6. Cookies
The Service uses functional cookies and local storage to remember your preferences. Analytics providers may set their own cookies. No advertising or cross-site tracking cookies are used.
7. Data I share
I do not sell or rent any data. The only third parties involved are the analytics and payment providers described above, and they receive only what is necessary to perform their function.
8. Your rights
Because I do not collect personally identifying information about Service users, there is generally nothing on my side to access, correct, or delete. For payment records held by Ko-fi, you can contact Ko-fi directly or email me and I will assist.
9. Children
The Service is not directed at children under 13, and I do not knowingly collect data from children. The Service can be used by anyone of any age without providing personal information.
10. Changes
I may update this Privacy Policy from time to time. The effective date at the top of this page reflects the latest version.
