Altitag is built so that the most sensitive thing you have — the photo — is processed entirely in your browser. This page lists exactly what does leave, and why.
Effective June 10, 2026
Altitag has no accounts and no signup. We never receive your photos: reading the image, extracting its EXIF data, drawing annotations and exporting the finished file all happen in your browser. Exports are re-encoded on your device with EXIF and GPS metadata stripped, so the file you download carries no location data. We use no cookies and we never sell or share personal data with anyone for advertising.
To find what's near a property, the editor sends the GPS coordinates from your photo — coordinates only, never the image — to data services:
Like virtually all web infrastructure, these services and our host (Cloudflare) see your IP address as part of serving the request and may keep transient operational logs.
We use a self-hosted instance of Plausible, a privacy-first analytics tool. It uses no cookies, collects no personal data, doesn't track you across sites, and gives us only aggregate counts (page views, referrers, country-level location). Your data never reaches a third-party analytics company.
The editor keeps a small amount of data in your browser's local storage: your Pro license key (if you have one) and editor preferences. It stays on your device; clearing site data removes it.
Pro is sold through Polar, our merchant of record. Polar handles checkout, billing and your payment details — we never see your card number. We validate your license key against Polar's API to enable Pro features, and we count Pro lookups per license key to enforce the monthly fair-use cap. See Polar's privacy policy.
If you write to us through the contact page, the name, email and message you provide are delivered to us via Web3Forms and used only to reply to you.
Because we don't hold accounts or personal profiles, there is usually nothing for us to export or delete — but if you believe we hold any personal data about you, or you have any privacy question, get in touch and we'll resolve it.
Altitag is not directed at children under 13 and we don't knowingly collect their data.
If this policy changes materially, we'll update the effective date above. Continued use of Altitag after a change means you accept the updated policy.
