Privacy Policy
Last updated June 14, 2026
Cini (“we”, “us”) is a social app for ranking the movies you watch. This
policy explains what we collect, why, and the control you have over it.
What we collect
- Account info — your email address and phone number, username,
display name, and optional profile photo.
- Your activity — movies you rank, sentiment and scores, Want to
Watch saves, lists, notes, favorite performances, watch dates and company,
likes, comments, and who you follow.
- Featured-release engagement — when we feature a new release in your
feed (always chosen from your own taste), we record whether it was shown,
opened, or saved. This is first-party data we keep to ourselves to
measure how features perform; it is never shared with advertisers or any third
party and uses no advertising identifier.
- Optional imports — if you upload a Letterboxd or IMDb export, we
read movie titles, years, ratings, and list names from the file to build
your queue. Files uploaded through the computer-transfer page are stored
privately for your account only and expire within a day.
- Contacts, only if you ask — the “find friends from contacts”
feature reads your address book on-device and sends the entries to our
server to check which belong to existing Cini accounts and show you the
matches. To let you know when a contact later joins, we keep a
one-way cryptographic hash of your contacts’ phone numbers — we do
not store names or readable phone numbers, and the hashes can’t be
reversed back into numbers. You can delete these hashes any time in
Settings → Privacy → “Remove synced contacts,” and they’re deleted with
your account.
- Approximate location, only if you ask — Showtimes can use your
location once (with your permission) to find your zipcode, or you can type
one. If you turn on theater alerts, we save that zipcode so we can
notify you when a movie on your Want to Watch is playing near you; turn it
off anytime in Settings. We never track or store your device’s GPS
location.
What others see
- Your rankings, Want to Watch, public notes, lists, and activity are
visible to people who can view your profile — everyone, or only approved
followers if your account is private.
- Personal notes are never shown to anyone but you.
- Stealth mode keeps an individual ranking off your friends’ feeds.
- Blocking a member hides the two of you from each other entirely.
What we don’t do
- We don’t sell your data.
- We don’t show third-party ads, use advertising identifiers, or share your
activity with advertisers. We may feature new releases picked from your own
taste and measure how they perform using our own first-party data.
- We don’t read your contacts or device location unless you explicitly
use the features above. From contacts we keep only un-reversible hashes of
phone numbers (no names) and only if you use Find Friends; location is only
ever turned into a zipcode (saved only if you turn on theater alerts).
Service providers
Your data is stored with Supabase
(database, authentication, and file storage). Movie titles, artwork, and
streaming availability come from TMDB;
your search queries are sent to TMDB to return results. Theater showtimes
come from Gracenote, which receives only the zipcode you search. This product
uses the TMDB API but is not endorsed or certified by TMDB.
Notifications
If you allow push notifications, we use Apple’s push service to deliver
them. You can turn each kind on or off in Profile → Settings →
Notifications, or disable them entirely in iOS Settings.
Deleting your data
Delete your account in Profile → Settings → Delete account — it
permanently removes your profile, rankings, notes, lists, and social
activity. You can also export your movies as Letterboxd-compatible CSVs from
Settings first. Questions or requests:
jtsilver123@gmail.com.
Children
Cini is not directed at children under 13, and we do not knowingly collect
data from them.
Changes
We’ll update this page when the policy changes and note the date above.
