Numeris — Privacy Policy
This policy explains what Numeris collects, why, where it goes, and how to get rid of it. It covers the Numeris iOS app published by Abdullah Faruk Çiftler, trading as zortproductions (Istanbul, Türkiye), who is the controller of the data described here.
Numeris is free to play, needs no sign-up, and is supported by advertising. Optional in-app purchases remove the ads or add coins.
No sign-up required. Automatic anonymous accounts. Delete anytime in two taps.
1. The short version
- Numeris never asks for your name, email address or phone number.
- On first launch it creates an anonymous account for you automatically, so your score survives reinstalling the app. That account is identified by a random code, not by you.
- The only thing you write that other people can see is your nickname.
- We show ads through Google AdMob. Personalised ads happen only if you allow tracking when iOS asks. If you buy Numeris Ad-Free, the ad software is not started at all.
- Purchases are handled entirely by Apple. We never see your card, your Apple ID or your billing details.
- If you allow notifications, we store a push token so we can send you occasional news about the game. We never use notifications for advertising. You can turn them off in iOS Settings at any time.
- You can delete your account and everything attached to it from inside the app, in two taps, with no email to anyone.
2. What we collect
2.1 The automatic account
The first time you open Numeris, the app creates an account on our server without asking you anything. It consists of:
| Data | Why it exists |
|---|---|
| A randomly generated address of the form <random>@numeris.device, and a random password | These are the account's credentials. The address is not a mailbox: it receives nothing, and nothing is ever sent to it. It exists because the account system requires an identifier. |
| A randomly generated nickname, which you can change | It labels your row on the leaderboard. |
| An avatar number and the language the app is running in | To show your chosen avatar, and to write notifications in your language. |
The credentials are stored in the iOS Keychain on your device. That is what lets your score come back if you delete the app and reinstall it.
2.2 Your play data
Stored against that account:
- Best score, best stage, total XP, games played, coin balance, league, last seen date
- A record of each finished run: score, stage, the highest difficulty level reached, how long it took, lives lost, best combo, whether it was solo or a duel, and the app version
- Achievements you have unlocked
- A ledger of coin movements: coins spent on perks and boosts, and coins added by a purchase (Section 2.3). Coins are also earned by playing, from the daily reward and by watching a rewarded ad.
2.3 In-app purchases
Numeris sells one non-consumable item (Numeris Ad-Free, which turns off all ads) and three coin packs. Every purchase is made through Apple's App Store:
- Apple processes the payment. Your card, your Apple ID, your name and your billing address stay with Apple. We never receive them. Apple's handling of this is covered by Apple's own privacy policy: www.apple.com/legal/privacy/
- When a purchase completes, Apple gives the app a signed receipt for it. The app checks that signature on your device and then grants what you bought.
- What reaches our server: for a coin pack, a line in your coin ledger saying which pack was bought, how many coins it added and your new balance. For every purchase attempt, a usage event recording the product and the outcome (purchased, cancelled, pending, failed), subject to the usage-data switch in Section 2.8.
- What does not: Apple's transaction identifiers and receipts are not sent to our server.
- Numeris Ad-Free is remembered on your device and by Apple against your Apple ID, which is why the Restore button on the Ad-Free screen brings it back on a new device without an account of ours being involved. If Apple refunds or revokes the purchase, the app reads that from Apple and the ads return.
Refunds are handled by Apple at reportaproblem.apple.com. We cannot issue them.
2.4 Multiplayer
If you play a 1v1 duel we store the room, the events exchanged between the two devices (joins, answers, finishes) and a record of the finished match. There is no chat and no messaging in Numeris. The only things that pass between two players are game moves and the nickname each has chosen.
2.5 Reports
If you report another player's nickname, we store who reported it, whose it was, the nickname as it read at the time, and the reason. We use it only to moderate names.
2.6 Kept only on your device
Some things never leave your phone:
- Daily reward streak: the day you last claimed, your current streak and your best streak.
- Boosts: how many Extra Lives and Head Starts you hold, and when a Double XP boost ends.
- Settings such as sound, music and the ad-free status.
2.7 Notifications
Numeris asks for permission to send notifications once, after you first claim a daily reward, and never at launch. If you say no, nothing in this section applies.
If you say yes, two kinds of notification can reach you:
- Reminders, such as the evening before a daily streak would break, or when a run was left unfinished. These are local notifications: your phone creates and delivers them itself, and nothing about them is sent to us.
- Push notifications from us: occasional news about the game, such as new features, events or an important change. To make these possible, iOS gives the app a push token, a random identifier that Apple issues for Numeris on this device. We store it on our server together with your account, the app version and the iOS version, and we use the app language stored with your account (Section 2.1) to write the message in your language. Apple delivers the notifications through its Apple Push Notification service.
The push token only lets us send a notification to this app on this device. It cannot be used to identify you outside Numeris, and we do not share it with anyone. We do not use notifications for advertising or marketing.
You can turn notifications off at any time in iOS Settings → Notifications → Numeris. When you do, Apple stops delivering them and tells us the token no longer works the next time we try, and we delete it.
2.8 Usage data (you can switch this off)
Numeris records its own product analytics: which screens are opened, which puzzle rules are answered correctly, when an ad was offered and whether it was accepted, whether a daily reward was claimed, whether notification permission was granted and whether a notification was opened, purchase attempts and their outcome (Section 2.3), and whether the app asked iOS to show the rating prompt. For ads, it also records the estimated value of each ad impression as reported by Google, which is how we know which ad placements are worth keeping. These events carry your account identifier, a random session identifier, your app version, platform and language.
When Numeris asks for a rating, iOS shows its own prompt. We are told only that we asked, never whether you rated or what you wrote.
This data is ours alone: it goes to our own server, it is not sold, not shared, and not used to follow you around other apps or websites. You can turn it off at any time in Profile → Privacy → Usage data.
2.9 Advertising
Numeris shows ads via Google AdMob, which is operated by Google. Two consent layers sit in front of it:
- If you are in the EEA, the UK or Switzerland, Google's consent form appears first and asks what you allow.
- A short Google message then explains what the advertising identifier is used for, and iOS asks whether Numeris may track you across other companies' apps and websites (App Tracking Transparency). If you say no, your device advertising identifier (IDFA) is not read and no cross-app tracking happens. The game plays exactly the same either way.
Google may process technical data such as your IP address, device type, coarse location derived from IP, and ad interactions in order to serve and measure ads. Google acts as an independent controller for this. Its own policy is here: policies.google.com/technologies/partner-sites
You can change your advertising consent at any time in Profile → Privacy → Ad privacy settings.
If you own Numeris Ad-Free, the ad software is not started, no consent form is shown and no ad requests are made.
2.10 Technical diagnostics
Google's ad software also collects technical data about how it is running: crash logs, performance data such as launch time, hang rate and energy use, and other diagnostic information. Google uses this to keep its software working and to measure advertising.
Numeris itself does not run a crash reporter and has no analytics SDK of its own. The diagnostics on this list come from the ad software, not from us.
2.11 What we do not collect
No real name, no phone number, no address, no payment or card data, no contacts, no photos, no microphone, no camera, no precise GPS location, and no health data. Numeris asks for none of these permissions. The only permissions it asks for are notifications (optional, Section 2.7) and tracking (optional, Section 2.9).
There is no email address for you either. The only thing that looks like one is the non-deliverable random string described in Section 2.1. It is an account identifier and cannot be used to contact you.
3. Where it is stored
Play data, accounts and push tokens are stored on our own server, running PocketBase, hosted in Germany (EU). Advertising data is processed by Google on its own infrastructure, payment data by Apple on its own, and push notifications are delivered by Apple. Any of these may be outside your country. Where data leaves the EEA or the UK, Google's and Apple's own transfer safeguards apply. See their policies linked above.
4. How long we keep it
- Your account and play data, including the coin ledger: until you delete the account.
- Push tokens: until you delete the account, or until Apple tells us the token no longer works (for example because you turned notifications off or deleted the app), whichever comes first.
- Usage analytics: kept in aggregate; individual event rows are tied to your account and are deleted with it.
- Finished duel records: these are also the other player's record of their own match, so they are kept, but your account reference is removed from them when you delete your account. What is left contains no identifier belonging to you.
- Reports you filed: deleted with your account.
- Data kept only on your device (Section 2.6): until you delete the account in the app or delete the app.
- Purchase records held by Apple: kept by Apple under Apple's policy. Deleting your Numeris account does not remove them.
5. Deleting everything
Open Profile → Account → Delete my account, confirm, and the following happens immediately:
- Your account is deleted from our server, and with it your nickname, scores, run history, achievements, coin ledger, push tokens, rooms, duel events, usage events and any reports you filed.
- The credentials in your device's Keychain and all local game data are erased, including your daily streak and boosts. Any scheduled reminders are cancelled. The app goes back to a first-launch state.
- Duel records keep only the anonymous remains described above.
This cannot be undone; there is no recovery path and no grace period. You do not need to email anyone, and we cannot do it for you. The button is the whole mechanism.
Purchases after deletion: Numeris Ad-Free belongs to your Apple ID, not to your Numeris account, so you can get it back with the Restore button after deleting. Coins bought with coin packs are part of the coin balance and are deleted with the account. Deleting the account does not refund them. Refunds are handled by Apple (Section 2.3).
If you simply delete the app without using that button, the account stays on our server (and your score returns if you reinstall). Use the button if you want it gone.
6. Children
Numeris is rated 4+ and is suitable for children, but it is not a Kids Category app and it is not directed primarily at children under 13. It contains third-party advertising and optional in-app purchases. Purchases go through Apple, so the Ask to Buy and Screen Time controls a parent has set up on a child's device apply to them.
We do not knowingly collect personal information from children, and the app is built so that there is nothing personal to collect: no sign-up, no contact details, no chat. The one field a child could type into is the nickname, and it is filtered. Names containing profanity, phone numbers, email addresses, links or messaging-app handles are rejected before they can be saved, and every player can report a name they think should not be there.
If you believe a child has provided personal information through a nickname or a report, write to contact@zortproductions.com and we will remove it.
7. Your rights
Depending on where you live, you have the right to access, correct, delete and export your data, to object to processing, and to withdraw consent.
In practice: deletion and consent withdrawal are built into the app and iOS (Sections 2.7, 2.8, 2.9 and 5) and are the fastest route. For anything else, such as a copy of your data, a correction or a complaint, write to contact@zortproductions.com. We answer within 30 days.
If you are in the EEA or the UK, our legal bases are: contract (running the game, leaderboard and duels, and delivering what you bought), legitimate interest (keeping the leaderboard free of abuse, keeping the game working) and consent (personalised advertising, usage analytics, notifications). You may lodge a complaint with your local data protection authority.
If you are in Türkiye, the same applies under KVKK No. 6698; requests may be sent to contact@zortproductions.com, and complaints to the Kişisel Verileri Koruma Kurumu.
8. Security, honestly stated
Traffic between the app and our server is encrypted with HTTPS. Accounts can read and write only their own records; the leaderboard is served by a view that does not contain email addresses or credentials at all. Push tokens are readable only by the account they belong to and by us. Purchase receipts are verified on the device using Apple's signatures, and a purchase whose signature does not check out is not granted.
No system is perfectly secure. What limits the damage here is that we hold so little: there is no real name, email, phone number or payment detail in Numeris to lose.
9. Changes
If this policy changes materially we will update the date at the top and note the change in the app's release notes. The current version always lives at zortproductions.com/numeris-privacy-policy.
18 September 2026: added in-app purchases (Section 2.3), data kept only on the device (Section 2.6), notifications including push tokens (Section 2.7), and the new usage events (Section 2.8).
