Privacy Policy
Last updated November 6, 2026
The short version
Sim Sunday collects the minimum needed to run online leagues and the Daily Challenge. We don't sell data, show ads, or track you across apps and websites.
What we collect
- Account identifier. If you use Sign in with Apple, we receive a stable, app-specific identifier from Apple (and your name only if you choose to share it). We never receive your Apple ID password. If you share a private relay email, we do not store it.
- Display name and team names you choose, shown to other players in your leagues and on leaderboards.
- League chat messages you send in a league with other players, shown to the people in that league.
- Your age range (never your birthday), from Apple, so players under 13 don't get chat and parents can say yes or no to it.
- Gameplay data: leagues, draft picks, lineups, trades, and Daily Challenge results, including a Daily Challenge you played offline and the app sent in later.
- Push notification token, if you allow notifications, to tell you when it's your pick, a trade arrives, or a friend posts a Daily score, and, if you switch it on, when there's a new league chat message.
- Which days you open the app (and on a Sunday, whether it was before 11 AM your time), and which of our notifications you open, to keep the one-a-day limit and to count, on our own server, how many people come back. No third party sees it.
- Your phone's offset from UTC (for example, 5 hours behind), so notifications never arrive between 10 PM and 9 AM your time. This is not your location.
- Friends you add with a friend code, so you can see each other's Daily scores.
- Reports and blocks. When you report a name or a message, we keep who reported it, who it was about and where. When you block someone, we keep that. Reports other people make about you are kept too. Each new report is sent to us as a notification, through a notification server we run ourselves, so we can review it; the notification is not kept once it is sent.
- Server logs. Our web server logs your IP address, the page or feature you asked for, the time and your app version, and keeps them 14 days for security and debugging. Our game server's own log names account IDs, never IP addresses or messages, and is kept 7 days.
What we don't collect
- No location, contacts, photos, health, financial, or browsing data.
- No advertising identifiers. No third-party analytics or ad SDKs.
Purchases
Sim Sunday Pro is purchased through Apple. Apple processes payment; we never see your payment details.
Solo and Nearby leagues
Solo leagues are stored only on your device. Nearby leagues are played between phones in the same room over peer-to-peer Wi-Fi, with one phone hosting: team names, picks and lineups go only between those phones, nothing reaches our server, and the league is saved on the host's phone. The first time you host or join, iOS asks to let Sim Sunday find devices on your local network. It is used only to find and talk to Sim Sunday players nearby.
Playing the Daily Challenge offline
So a Daily played with no signal can still count, the app keeps a ticket for today's and tomorrow's Daily, fetched from our server while you're online. When you're back online, the app sends that run's draft picks and lineup moves to our server, which plays them again to check the score. It is the same gameplay data an online Daily sends.
Bringing in a Sleeper or ESPN league
Sleeper usernames and league data are public. When you bring in a Sleeper league, the app sends the username you type only to Sleeper, and reads the league's public data on your phone. When you bring in an ESPN league, the app sends the league link or ID you type only to ESPN, and reads that league's public data on your phone. It works only with leagues set to be viewable to the public, and the app never asks for your ESPN login or stores any ESPN sign-in. Playoff Odds and playing it out on your own stay on your device; nothing about the import reaches our server. The one exception is Play It Out Together: hosting it sends that league's team names, owner names, rosters, schedule and results to our server so friends can claim their teams. We store them like any group league, and they are deleted when the host deletes their account. Sim Sunday is not affiliated with Sleeper or ESPN.
Shared odds links
When you share Playoff Odds, the link itself carries the card: the league's name, the week, and each team's name and odds. To make the link, the app sends the card to our server, which signs it and sends it straight back. We don't keep a copy. To show the link's preview picture, our server keeps the rendered image for up to 30 days, then deletes it.
Apple Intelligence
On supported iPhones, announcer commentary is written by Apple's on-device model from results already on your phone. That text and its inputs never leave your device and are never sent to us.
League chat
Messages you send in a league's chat are stored on our server with your account, and shown to the people in that league (except anyone who has blocked you). We keep each message for 30 days, then delete it; a league's messages are deleted with the league, and yours with your account. If someone reports a message, we keep a copy of it with the report for up to 180 days so we can act on it. Chat notifications are off unless you switch them on under Profile → Nudges.
Your age range
Before League Chat opens, the app asks Apple to share your age range (for example, 13 to 15, or 18 and over). Apple never shares your birthday, and neither do we. The app sends our server only that range and, for players under 18 where the law asks for it, whether a parent or guardian said yes to chat, plus Apple's ID for your download of the app, so we can turn chat off if a parent later withdraws consent. Players under 13 never get chat. The rest of Sim Sunday works the same at every age. Your age range is deleted with your account.
Streaks, Divisions and notifications
Your Daily streak and weekly Division are worked out from your Daily Challenge results. Sunday Kickoff is scheduled on your phone; Friend Alerts come from our server. Each has its own switch in the app under Profile → Nudges, and you'll get at most one a day.
How long we keep it
- Your account, display name, team names, friends, gameplay, streak and Divisions: until you delete your account. A guest account (one without Sign in with Apple) is deleted after a year without use, or when its sign-in expires.
- A league nobody has played in for a year is deleted.
- League chat messages: 30 days, and at most the newest 2,000 in a league.
- Reports: the copy of a reported message 180 days, the report itself a year.
- Which days you opened the app, and which of our notifications you opened: 400 days.
- Your age range and whether a parent or guardian said yes to chat: until you delete your account (each new answer replaces the last). If a parent withdraws consent, Apple's ID for that download of the app is kept 400 days, with no account attached, so chat stays off if the app reports it again. Apple's notifications to our server: 30 days.
- Push notification tokens: until you delete your account, iOS tells us a token no longer works, or your phone hasn't sent it for 180 days.
- Offline Daily Challenge tickets: 30 days. Shared odds preview pictures: 30 days.
- Server logs: 14 days (web server) and 7 days (game server).
- Backups: our database is backed up every night, encrypted, and each backup is deleted after 14 days. Data you delete can stay in a backup until that backup is deleted, so for up to 14 days.
Who else handles it
Our server and its backups run on computers we rent from Hostinger and on our own. Notifications go through Apple's push service, which carries each notification's text to your phone. Sign in with Apple and purchases are handled by Apple. Nobody else receives your data, and we never sell it.
Deleting your data
Delete your account any time in the app under Profile → Delete Account, or email support@simsunday.com. This deletes your account and everything tied to it on our servers: your Sign in with Apple identifier, display name, friend code and friends, Daily Challenge history, streak, Division results, chat messages, blocks, age range, notification settings, push tokens and the days you opened the app.
Leagues you host that haven't started yet are deleted, and so are leagues you brought in from Sleeper or ESPN and host. In a league with other people that has already started, a computer manager takes over your team under a plain name like "Team 3", so their season can go on; your name and your team's name are removed from it (a league you hosted keeps its own name). Reports you made stay, but no longer name you. If someone reported you, that report and its copy of your message are kept until they expire (180 days for the copy, a year for the report), so we can still act on abuse.
Deleted data can remain in our encrypted backups for up to 14 days. Solo and Nearby leagues saved on your phone stay there until you delete them or the app.
Children
Sim Sunday is not directed to children under 13 and we do not knowingly collect their personal information. If the age range a phone shares says the player is under 13, League Chat stays off for good, and we keep only what the game needs to run: the account, its leagues and its scores. We never ask anyone for a real name, an email address or contact details. If a parent or guardian withdraws consent, chat turns off and the rest of the account stays until it is deleted. A parent can delete the account any time under Profile → Delete Account, or by emailing support@simsunday.com.
