This site

This site sets no cookies and contains no advertising trackers.

Android list: if you leave your email to hear about the Android launch, it is stored on our server in France with the site’s language, only to send you that message. It is never sold or used for anything else. You can ask for its deletion at any time by writing to contact@calvap.com.

Audience measurement: Umami, installed on our own server, cookieless and without personal data. It counts visits and clicks on “Download” without identifying you or following you across sites.

Not a medical device

Calvap is a photo journal to follow how your hair changes. The app makes no diagnosis, computes no risk and recommends no treatment or dose. It doesn’t replace medical advice: talk about your treatments with a doctor or a pharmacist.

What stays on your phone

Your photos, questionnaire answers, treatments, reminders and PDF sheets are stored on your phone. Photos only go to your camera roll if you export them. Without an account, none of it leaves the phone, except the transfers below, and deleting the app deletes it all.

What leaves, and when

The AI analysis: the photos of the analysed session and your tracking profile (sex, year of birth, how long and how fast the loss has been, relatives affected, current treatments with dose and duration, how they are taken), sent when you run the analysis (or after each session if you chose automatic analysis) to our provider OpenAI, in the United States, with your consent, asked before your first analysis. Calvap doesn’t keep them; OpenAI then deletes them, at the latest 30 days later (the time needed to detect abuse), and doesn’t use them to train its AI. You can withdraw your consent at any time in Settings › AI analysis. With them go an anonymous identifier of your phone, to count analyses, and your subscription’s, to check Calvap+.

“Write to us”: your message, your email if you give it, the app version, the phone model, references of the latest errors (if error reports are on) and an anonymous phone identifier (to allow 5 messages a day), forwarded by email to the Calvap team, never stored elsewhere.

Your answer to “Where did you hear about Calvap?”, without your identity.

Once a week, anonymous statistics about the past week, with no identifier at all: sex, age range, goal, types of treatments tracked (never the names you type), number of app opens, time spent, photo sessions, doses checked off and analyses, app version, Calvap+ subscription or not. With these statistics, each time a Calvap+ offer is shown and each purchase (the plan, without your identity). You can stop this in settings.

At most once a day, the app asks our server for the list of “Reads” articles, telling it nothing about you: it receives them all and picks the ones relevant to you on your phone. At each launch, it also asks our server whether an app update is available, telling it nothing about you.

Calvap+ backup

With Calvap+, you can create an account (Apple, Google or email link, no password) to back up your tracking and photos. They are encrypted and hosted by Amazon Web Services in Stockholm (European Union). If Calvap+ ends, your backup is kept 90 days, you get an email 14 days before, then it is deleted. Deleting your account, in Settings, erases your backup right away.

Error reports

When the app hits an error, a technical report is sent to our provider Sentry, on servers in Germany: the error, the screen it happened on, the app version and the phone model. It contains no photo, no questionnaire answer, no treatment and no identifier. You can turn this off in Settings.

Purchases

Calvap+ purchases go through the App Store or Google Play, and our billing provider RevenueCat. It receives an anonymous identifier, or your Calvap account’s if you created one, your purchases and your answer to “Where did you hear about Calvap?”: no photo, no health data.

Calvap+

Calvap+ is offered as a monthly or yearly subscription, renewed automatically unless cancelled at least 24 hours before the end of the period, or as a one-time lifetime purchase. The price is shown in the app before any payment. The subscription is managed and cancelled in your App Store or Google Play account settings. When it ends, nothing is deleted from your phone; only the online backup follows the 90-day rule.
