What the app collects

Rate reports you send: the currency, the value and the city. Confirmation votes. Messages you send from the Contact screen, with the reply email if you add one. A random code created for this installation and a technical session ID, used to protect the rate from manipulation. When you sign in with Google: your name, your email address, your alerts (currency, direction and level) and a count of what you sent. Crash reports: phone model, Android version, app version and the error.

What it does not collect

No access to your geographic location. No access to contacts. No photos. Your reports appear as numbers within the community, without your name or your photo.

How the data is used

The data serves one purpose: computing a reliable community rate and keeping it honest. It is never sold and never shared for advertising.

Where it is stored

On Google Firebase servers. We delete reports and messages after 180 days and votes after 30 days; crash reports are kept for 90 days. Your alerts are kept on your phone; when you are signed in they are also copied to your account so they follow you to a new phone, and each alert level is registered with Firebase Cloud Messaging so the push can reach you. Messages are also emailed to our support mailbox through our email provider, Brevo, so we can answer them. Your preferences stay on your phone.

Deleting your data

Deleting your account from the Account screen permanently removes your sign in data, your profile, your synced alerts and the messages tied to your account. The prices and confirmations you sent stay in the market history, linked to neither your account nor your phone, until they are deleted on the schedule above. To delete copies of your messages from our support mailbox, write to contact@chhaldar.com.
