FAQ
Frequently asked questions
How does the ranking system work?
Rank Your Movies uses a pairwise comparison method inspired by Flickchart. You're shown two films side by side and pick your favourite. Over time, these head-to-head choices build a personalised ranked list — no star ratings needed.
What is the Elo rating system?
Elo is a mathematical rating system originally used in chess. Each film starts at a rating of 1500. When you pick a winner, the winner gains points and the loser loses points — how many depends on the difference in their current ratings. Films rise and fall naturally as you make more comparisons.
How many duels does it take to get an accurate ranking?
Rankings become more accurate with more duels. Generally, 10–20 per film produces reliable results. There's nothing to configure: the Duel tab already favours the films you've compared least, and about a third of the time it pits two of your top films against each other, since that's where the ordering is hardest and matters most.
Can I re-rank a film I've already compared?
Yes. Tap any ranked film in the Ranking tab to start a re-ranking session. You'll play it against five opponents, and they aren't picked at random: it starts near the middle of your list and narrows after every answer, the way you'd find a word in a dictionary. Five duels are enough to place a film to within a few positions.
How do I add films to rank?
The first time you open the app, a grid of well-known films gets you started — tap the ones you've seen and they become your first ranking. After that, use the Search tab to find anything else from a catalogue of 359,000+ titles via TheTVDB, in any language, and tap a film to add it. You can also save films to your watchlist to see later.
What is the watchlist for?
The watchlist holds films you're interested in before you're ready to rank them. Tap the heart on any card or search result to add one. Once you've seen it, open the list from the You tab and add it to your ranking.
What is Discover?
Once you've ranked five films, the Discover tab starts suggesting what to watch next. It reads your own ranking — which films you put above which — and asks a language model for titles that fit, each with one sentence on why it picked that film for you. You can rank a suggestion straight away, save it to your watchlist, or say you've already seen it.
Only film titles, their ratings within your list, your watchlist and the films you've turned down are sent. Your name, email and account ID are not. See the privacy policy below.
Is my data backed up?
Yes. Your ranking, your duels and your watchlist are stored on our servers, not just on your phone, so they survive a change of device. If you sign in with Apple, Google or GitHub, you get them back by signing in on any iPhone.
How do I delete my account or data?
In the app, the You tab has "Reset all data" and "Delete account". You can also email support@rankyourmovies.app with the subject "Delete My Account".

What data we collect
Rank Your Movies collects only the data necessary to provide the ranking service:
- Account information — If you sign in with Apple, Google or GitHub, we receive the name and email address that provider gives us. This is used solely to identify your account. Sign in with Apple lets you hide your real address, and the app works normally with a relay one; GitHub may give us none at all, and that works too.
- Rankings and duels — Your ranked films, Elo ratings, and duel history are stored in our database (Supabase) so your rankings sync across devices and persist between sessions.
- Watchlist — Films you save for later are stored in your account.
- Usage data — The app records where you get to: that it opened, that you reached the first-run grid, how many films you picked, that you started or finished a run of duels. Never which films they are, or how you rank them. Each event carries your account ID, not your name or your email. You can turn it off under You → settings → Share usage data, and it stops sending the moment you do.
Movie data
Movie metadata (titles in several languages, posters, synopses, genres) is fetched from the TheTVDB API.
Anonymous use
You may use the app without signing in. We still create an anonymous account for you, so your rankings are saved and synced the same way — it simply holds no name, no email and nothing you did not enter yourself. Your films are stored on our servers under that account, not only on your device.
The key to an anonymous account is kept in your device's keychain, so deleting the app loses access to it. Signing in at any point attaches that same account to you permanently, keeping everything you ranked before.
Discover recommendations
When you open Discover, we send the titles in your ranking together with their ratings, your watchlist and the films you've already turned down to a language model that suggests what to watch next. Your name, your email address and your account ID are never included. The request is made by our server, not by your device, and the reply is only used to produce the suggestions you see.
How we use your data
Your data is used exclusively to:
- Save and display your rankings
- Sync your data across your devices
- Provide duel history
- Produce your Discover recommendations
- Understand where people give up on the app, so we can fix it
We do not sell your data, and we never use it for advertising or profiling. Only two things leave our own systems: the Discover request described above — and only the parts listed there — and the usage data, which you can turn off.
Third-party services
- Supabase — Database and authentication provider. Data is stored on Supabase servers. See Supabase's privacy policy.
- TheTVDB — Movie data API. We only ask it for data; nothing of yours is sent to it. See TheTVDB.com.
- OpenRouter — Routes the Discover request to a language model. It receives the film titles in your ranking with their ratings, your watchlist and what you've turned down. It does not receive your name, your email or your account ID. See OpenRouter's privacy policy.
- PostHog — Analytics for this website and for the app, with data hosted in the European Union. From the website it receives which pages are visited and where visitors arrive from, with no cookies. From the app it receives the usage data described above, carrying your account ID. In both cases it derives an approximate location from your IP address — country and city, never a precise position — and stores it; the app never uses GPS and never asks you for location permission. In neither case does it receive anything from your rankings, duels or watchlist. See PostHog's privacy policy.
- Apple, Google and GitHub — Optional sign-in providers. See the privacy policies of Apple, Google and GitHub.
This website
This site — separately from the app — measures its visits with PostHog, hosted in the European Union. It runs without cookies: it stores nothing whatsoever on your device, and counts each visit through an identifier computed on the server with a salt that is rotated daily, so not even we can recognise you from one day to the next. This site sets no cookies at all, which is why it never asks you to accept anything. The app measures its own thing separately, and is turned off separately, as described above: nothing from your rankings, duels or watchlist reaches either of them.
Data retention and deletion
Your data is retained as long as your account is active. To delete your account and all associated data, use "Delete account" in the You tab, or email support@rankyourmovies.app with the subject "Delete My Account".
