What Paceberg stores about you

What is stored

• Your export zip, byte for byte as Strava made it. It holds your activities, their GPS tracks and your heart rate. GPS tracks usually show where you live.
• The tables built from it: activities, laps, the second-by-second streams, and the errors found while reading the files.
• Your email address, so Chirag can make you an invite link.
• A hash of your invite link and of your session cookie. Not the link or the cookie itself. A copy of the database cannot be used to sign in as you.
• One row per import: when it ran, how long it took, how many activities and files it read, and the error message if it failed.

Where it is stored

The zip and the tables are in a Cloudflare R2 bucket. The email address, the hashes and the import rows are in a PostgreSQL database on a server Chirag rents. Cloudflare is the only other company that holds your data.

Who can see it

Only you. Every page and every API call works out who you are from your session cookie and reads only your own folder; no request can name someone else's. SQL runs inside your browser, so your data is not queried on the server.

Chirag runs the server, so he can technically reach the storage and the database. He does not look at your data, but you are trusting a person, not a system.

No tracking

No analytics, no advertising, no cookies except the one that signs you in, and no fonts or scripts loaded from anyone else.

Downloading and deleting

On the data page you can download your original zip and every file Paceberg built from it. The same page deletes everything: the files in storage, the import rows and your account. That cannot be undone.

One exception: if an upload is still in flight when you delete, that one file can take a few more minutes to disappear. Nobody can reach it in the meantime, because your account is already gone.

This is an early version

Paceberg is invite-only and run by one person. Anyone who has your invite link can sign in as you, so keep it to yourself. Write to Chirag if you want your data gone and cannot do it yourself.
