When you create a PiLNK account, we collect:

• Your callsign (chosen by you)
• Your email address
• A hashed (encrypted) password — we never store your password in plain text
• Optional: location, bio, and profile details you choose to provide

When you use the PiLNK platform, we also collect:

• Forum posts, replies, and messages you send
• Watchlist items and alert preferences
• Node registration details (if you register a Pi node)
• Aircraft telemetry data received by your node (ADS-B position reports)
• Your last seen timestamp for online status
• Basic usage data (page visits via Google Analytics)

If you sign in with Google, we receive your name and email address from Google. No other Google account data is accessed.

Your data is used to operate the PiLNK platform and nothing else:

• To create and manage your account
• To display your callsign, posts, and profile within the community
• To send watchlist alerts when tracked aircraft enter your coverage area
• To contribute your node's ADS-B coverage to the shared network map
• To send account-related emails (verification, password reset)
• To display anonymous usage statistics (Google Analytics)

We do not sell your data. We do not share your data with third parties except as required to operate the service (e.g. email delivery). We do not serve advertising.

ADS-B aircraft telemetry data received by your node is shared with the PiLNK community network. This data originates from publicly broadcast radio signals and does not contain personal information.

You can delete your account at any time by contacting us. Upon deletion, your personal data will be removed from our systems within 30 days.

You can update or correct your profile information at any time from your profile page.

We retain forum posts after account deletion in anonymised form to preserve community discussions, unless you specifically request full removal.

PiLNK uses a session cookie to keep you logged in. No tracking cookies are used beyond Google Analytics, which collects anonymous page view data to help us understand how the platform is used.

PiLNK products are ad-free. No advertising networks or data brokers receive your information.

Passwords are hashed using bcrypt. All connections are encrypted via HTTPS. We use CSRF tokens to protect against cross-site request forgery. We do not store payment information — all transactions are handled by third-party processors.
