Filiation is not released yet. This page says what is true of this website today, and what the app is being built to do. It will be rewritten to describe the released app, in the same change that ships it.
The app
Filiation is being built with no account, no server of ours and no analytics or tracking code. Your tree is stored on your device. Sync and sharing, when they arrive, go through your own iCloud account and stay off until you turn them on; we never see what is in them. Crash reports, if you allow them, go to Apple and not to us.
This website
This site counts visits with Cloudflare Web Analytics, which sets no cookies and does not follow you across other sites, so there is no consent banner. Fonts and images are served from this site itself; no other third party is contacted when you read it.
Feedback form
The feedback form sends something only when you fill it in and press send. The app never sends feedback itself: it opens that page in your browser and stops.
We receive what you typed, the subject and details, and your email address if you chose to give one. Opening the
form from the app also fills in four technical facts: your Filiation version, your system version, your device’s
model identifier (like Mac16,10) and your language. They arrive in the web address itself, so you can
read them in the address bar before anything is sent, and the form shows them as ordinary fields you can edit or
clear. That is the whole list: never a name, a date or anything else from your tree.
Submissions are stored in a Cloudflare D1 database in Western Europe, with the two-letter country your request came from, and emailed to support@mgcrea.io so we can reply. The form sets no cookie, and the code that handles a submission never reads or stores your IP address. Submissions are never used for marketing, sold or shared. To have one deleted, email us.
