External Data Processors
The services that process personal data on behalf of AvioADSB (processors under Article 28 of the GDPR), and the other third parties your browser connects to when you use the site. The privacy policy says what each kind of data is for and how long it is kept.
| Processor | Purpose | Data processed | Location | Privacy policy |
|---|---|---|---|---|
| Resend | Transactional email delivery (account verification, password reset, inactive-account warnings) | Email address, email content | USA (EU SCCs apply) | resend.com/privacy |
| PostHog | Product analytics (page views, clicks, sessions) | IP address, browser and device data, pages visited, interactions; a cookie identifier and session recordings only with consent | EU (Frankfurt) | posthog.com/privacy |
| Cloudflare | CDN, DDoS protection, DNS proxying | IP addresses, HTTP request metadata (not stored by us) | Global / EEA nodes | cloudflare.com/privacypolicy |
| PostgreSQL (self-hosted) | Primary database — stores account, station, contact and host-application data | All user-generated data | EU (Dokploy-managed VPS) | Self-hosted — no third-party sub-processor |
| VPS hosting provider | Infrastructure hosting — the server that runs AvioADSB (deployed with Dokploy, which runs on that server) | All data stored on the server | EU | Under the provider's data processing agreement |
| OpenFreeMap (map tiles) | Map tiles for the live aircraft, receiver and coverage maps | IP address of the browser loading tiles (their access log only, not shared with us) | Global CDN | openfreemap.org |
| OpenStreetMap (map tiles) | Map tiles, only if you choose an OpenStreetMap layer on the live map | IP address of the browser loading tiles (their access log only, not shared with us) | Europe | osmfoundation.org |
Changes to this list
We update this list whenever we add or remove a processor. Material changes are communicated to registered users by email. Fonts, scripts and the API documentation are served from our own server, so no font or script CDN receives your IP address.
