Privacy policy
This page explains, in plain words, which data is stored when you create a calendar, why, for how long, and what you can do with it.
Last updated: 23 August 2026
What is stored
What you enter yourself: the calendar name and dates, the first names of parents and children, custody rhythms, school holidays, holiday agreements and hand-added dates, parents' commitments (a label, dates), notes, and a timestamped history of changes. That history holds no identity: Alternoo does not know who holds a link.
The recovery email address, only if you enter it in the settings. It is used to send your links back if you lose them, and for nothing else.
The language and time zone of the calendar, to show the right dates.
Technical server logs (IP address, requested page, timestamp), kept briefly for security and to keep the service running.
Tip: first names are enough, no need for surnames or addresses.
Why
Only to run the service you ask for: show the calendar, share it by link, produce the calendar subscription feed, and email your links back if you lose them (performance of the service, article 6.1.b GDPR). Technical logs rely on our legitimate interest in securing the service (article 6.1.f).
No advertising, no profiling, no resale or transfer for commercial purposes.
Who can access it
Anyone who holds a link: the edit link, the read-only link or the calendar subscription link. These links are long and impossible to guess, but if you share them, recipients see the whole calendar, parents' commitments included. You can regenerate each link at any time from the “Share” button.
Our host stores the data on our behalf. Recovery emails go through an email delivery provider, which only receives the address and the links.
The site's fonts are loaded from Google Fonts: your browser then sends your IP address to Google, as with any site using that service.
Cookies
Alternoo only uses strictly necessary technical cookies (session, protection against forged requests). No advertising cookie, no audience measurement, no third-party tracker: that is why there is no consent banner.
For how long
As long as the calendar exists. You can delete it at any time from Settings > Data: all its content is erased immediately and permanently. Server security backups are rotated regularly and only serve to restore the service after a failure.
Your rights
Access and portability: export the whole calendar as JSON (Settings > Data). Rectification: everything can be edited with the edit link. Erasure: delete the calendar from the settings. For any other request (objection, restriction), get in touch with us.
You can also lodge a complaint with the Data Protection Authority (Belgium) or the CNIL (France).
Children
A calendar holds information about children (first names, where they sleep), entered by their parents. We ask you to stick to what is strictly needed to organise custody.
Changes
This policy may evolve with the service. The date of the last update is shown at the top of the page.
