The short version

  • We never ask for your name, email, contacts, or location, and there is no account. We do not sell data.
  • There are no ads, no advertising or social-media SDKs, and no tracking. The app contains one third-party service: RevenueCat, which keeps our purchase records and, since version 1.0.1, a few anonymous flags about the parent setup flow.
  • The app never asks for permission to track you and does not use the advertising identifier (IDFA).
  • Your child's progress lives on your device and, if you use iCloud, in your own iCloud account. We cannot see it.
  • Purchases are handled by Apple. We never see your name, address, or payment details; we see only an anonymous purchase record (which plan, when, and in which country's App Store).
  • Listening games work offline after installation. Purchases, restoring purchases and iCloud sync need an internet connection.

Who is behind Tonmi

Tonmi is developed and published by Barış Ercan, an independent developer. If you have any question about privacy, write to hello@tonmi.app.

What the app stores on your device

To work, Tonmi keeps a small amount of information in the app's own storage on your iPhone or iPad:

  • Settings you choose in the parent corner (sessions before a nap, nap length, how new colors are added, questions per session, daily goal).
  • Progress: the current level, how many sessions were played each day, and recent answers used to calculate accuracy and unlock the next color.
  • Milestones and weekly totals: earned milestones and their dates, plus stored session and answer counts. The weekly chart shows practice activity.
  • Stickers your child has collected.
  • A random identifier created on the first launch, in case we ever want to count anonymous usage without any personal data. It is not derived from your device, is not linked to you, and today is never sent anywhere. The purchase-records component described under "Purchases and subscriptions" creates a separate random identifier of its own.
  • The highest attribution value reported so far (see "Ad attribution" below), so the app never reports it twice.
  • Notifications, if you allow them: a short weekly report on Sunday evening once a plan is active, or, before a plan starts, one reminder a day about Tonmi for up to seven days. iOS schedules them on your device and the text is computed there; nothing is sent to us. You can turn them off in the parent corner or in iOS Settings.

None of this identifies you or your child. Deleting the app deletes all of it. You can also reset statistics, stickers, or everything from the parent corner at any time.

iCloud sync

If your device is signed in to iCloud, Tonmi stores the same progress and settings in your own iCloud account using Apple's key-value storage, so a second iPhone or iPad with the same Apple Account picks up where the first one left off.

This data belongs to your iCloud account. It goes from your device to Apple's servers and back; it never passes through us, and we have no way to access it. Apple's handling of iCloud data is described in Apple's privacy policy.

Resetting progress in the parent corner also clears the synced copy. Signing out of iCloud on a device stops syncing for that device.

Purchases and subscriptions

Tonmi Plus is sold through Apple's App Store as in-app purchases (monthly and yearly subscriptions, or a one-time lifetime purchase). Apple processes the payment and keeps your billing information. We never receive your name, address, email, or payment details.

The app asks Apple's StoreKit only whether the current Apple Account has an active purchase or free trial, so it can unlock the game. That check contains no personal information and works with Family Sharing.

To validate purchases and keep accurate sales records (revenue, trial conversions, refunds), the app includes RevenueCat, a subscription-infrastructure provider that processes data on our behalf. When the app starts, and when you buy or restore a plan, RevenueCat receives: a random identifier created for this installation; Apple's vendor identifier for the device (IDFV, which only our own apps can read and which cannot be used to follow you across other companies' apps); your App Store purchase records for Tonmi (product, price, dates, trial and renewal status, App Store country); and basic technical details (app version, iOS version, device model, language settings). Since version 1.0.1 the app also stores, on the same anonymous record, a few flags about the parent setup flow: the onboarding page you reached, how many times the plans screen was shown or closed, which plan you tapped, and how many game sessions have been completed. Version 1.0.2 adds the time of the first and the latest session and the number of days with a session. These are plain counts and times: nothing about which chords were played or which flags were tapped. Version 1.1.0 adds a few more: your one-tap answer to "Where did you hear about Tonmi?" (or that you skipped it); the campaign name of an offer code, if a plan started with one (never the code itself); how often a milestone card was opened and shared, which milestone it was, and the kind of app it went to (such as WhatsApp, never to whom); how the short demo ended; whether the free round offered after the plans screen was closed was played, and your one-tap answer to why you didn't start a plan (or that you skipped it); whether the parent gate before the plans screen was passed; whether a free trial was available; whether notifications are allowed; the app version first installed; how many times the parent corner was opened; and how many times the app asked Apple to show its rating window, on which occasion (weekly report, sharing, parent corner) and when. Any rating you give goes to Apple and never reaches us. They tell us where parents stop before starting a trial, and whether families who play keep going. They are not linked to who you are, and they say nothing else about your child. As with any internet service, your IP address is processed to deliver the request. RevenueCat receives no name, email, Apple Account, or advertising identifier, and nothing about your child beyond those counts. We use this data only to run and understand Tonmi's sales. It is never used for advertising or profiling and is never sold. See RevenueCat's privacy policy.

You can review, change, or cancel subscriptions at any time in your App Store account settings: Manage subscriptions. Refunds are handled by Apple: Request a refund from Apple.

Ad attribution (no tracking)

Tonmi does not use the advertising identifier, never shows the "Ask App Not to Track" prompt, and contains no advertising or social-media SDKs.

If we ever run an ad for Tonmi on the App Store or elsewhere, Apple's privacy-preserving attribution framework (SKAdNetwork / AdAttributionKit) may tell the advertising network that some install came from that campaign and reached a coarse milestone, such as "finished onboarding" or "made a purchase". These signals are generated and delivered by iOS, carry no identifier for you or your device, are delayed and aggregated by Apple, and cannot be linked back to you. We use nothing else.

If you installed Tonmi after tapping an ad on the App Store (Apple Search Ads), Apple's AdServices framework lets the app ask Apple which campaign that was. The answer contains campaign and keyword identifiers and no personal information. It is stored with the anonymous purchase record at RevenueCat so we can tell whether an ad paid for itself. This uses no advertising identifier and no tracking across apps.

Children's privacy

Tonmi is designed for children and built with children's privacy in mind. The game collects nothing about your child: no name, no age, no voice, no photos. What they play and how they answer never leaves your device or your own iCloud account. The only data the app sends out is the anonymous purchase and device record described under "Purchases and subscriptions", which includes a plain count of completed sessions and, if you share a milestone card, which milestone it was. Milestone cards are drawn on your device; we never receive the image.

The listening game requires no reading. Settings, purchases, and external links are behind a parent gate that asks a multiplication question. There is no chat, user-generated content, or external web browsing inside the app.

This website

tonmi.app is a static website. It sets no cookies, runs no analytics or tracking scripts, and loads no fonts or scripts from third parties. If you switch languages, nothing is stored.

The site is served by Cloudflare. Like any host, Cloudflare processes the technical data needed to deliver pages and protect the site from abuse (for example your IP address, for a short time); see Cloudflare's privacy policy. We do not receive or keep this data.

Data-protection laws such as the GDPR in the EU and the UK, Türkiye's KVKK and the US children's privacy rules (COPPA) ask us to state a few things plainly. Here they are.

  • Why we may process this data. Checking your purchase with Apple and unlocking the game is necessary to give you what you bought (performance of a contract). Keeping the anonymous purchase record at RevenueCat, and learning whether an App Store ad led to an install, is our legitimate interest in running Tonmi as a small business: understanding sales, handling refunds and support, and keeping the accounts in order. Notifications go out only with your permission, which you can withdraw at any time in iOS Settings. We never process anything for advertising, profiling or sale.
  • Children. The app does not knowingly collect personal information from children, and nothing on the child's screens sends data anywhere. The device identifier and the random installation identifier described above support only the app's internal operations (validating purchases and keeping sales records), which COPPA allows without parental consent; they are never used for behavioral advertising or profiling. Purchases and every other decision are made by an adult behind the parent gate.
  • Who receives data. Apple handles purchases, iCloud, notifications and ad attribution under its own privacy policy, as an independent company. RevenueCat, Inc. (United States) processes purchase records only on our instructions, under a data processing agreement, and may not use them for its own purposes. Cloudflare, Inc. (United States) serves this website. We use no other service provider and share data with no one else, unless the law requires it.
  • Transfers outside your country. RevenueCat and Cloudflare store data on servers in the United States. For families in the EU, the UK and Switzerland, these transfers are protected by the European Commission's Standard Contractual Clauses (with the UK addendum) in our agreements with these providers. Where Apple stores data depends on your Apple Account's region.
  • How long we keep it. Progress and settings stay on your device and in your iCloud account for as long as you keep them. The anonymous purchase record at RevenueCat is kept for as long as Tonmi is sold, so that purchases can be validated and refunds and support requests handled; after that, or earlier on your request, it is deleted. Apple's ad-attribution signals arrive aggregated and are kept only as part of that record.
  • Your choices. You don't need to give us anything to use Tonmi. Notifications are the only optional item, and you can decline them. You can delete all local data by deleting the app, clear the iCloud copy from the parent corner, and ask us to delete the purchase record.

Your rights

We hold nothing that identifies you or your child by name: no account, no email, no contact details. Deleting the app removes all local data, and the reset options in the parent corner clear the iCloud copy. The only record on our side is the anonymous purchase record at RevenueCat. To have it deleted, write to hello@tonmi.app with the order number from Apple's purchase receipt and we will remove it.

If you believe we have received personal information by mistake, or you have any privacy question, write to hello@tonmi.app and we will answer as quickly as we can. You also have the right to lodge a complaint with your local data-protection authority.

Under the GDPR and similar laws you can ask to see the data we hold about you, have it corrected or deleted, restrict or object to its processing, and receive a copy in a portable format. Because nothing we hold carries your name, the only way for us to find your record is the order number from Apple's receipt. We answer free of charge, as quickly as we can.

Changes to this policy

If the app ever starts collecting anything new — for example anonymous usage counts — we will update this page first and change the "Last updated" date. We will never add personal-data collection to child screens.

19 September 2026: the app now includes RevenueCat for purchase records and Apple's AdServices attribution for App Store ads, both described above. Notifications now include optional reminders before a plan starts.

25 September 2026: nothing new is collected. We added the section on legal bases, recipients, transfers and retention, listed your rights in more detail, and clarified that the purchase-records component uses its own random identifier.

2 October 2026: version 1.0.1 adds the parent setup-flow flags described in the RevenueCat section (onboarding page reached, plans screen shown or closed, plan tapped). Nothing is collected about children or play.

8 October 2026: the count of completed sessions, which the app has stored since 1.0.1, was missing from this page and is now described in the RevenueCat section. Version 1.0.2 adds the time of the first and the latest session and the number of days with a session. Still nothing about which chords were played or which flags were tapped.

15 October 2026: version 1.1.0 adds the answer to "Where did you hear about Tonmi?", the campaign name of an offer code, milestone card counts and the kind of app a card was shared to, and a few setup-flow flags (demo, free round and why-not answer, parent gate, trial availability, notifications, first installed version). All are described in the RevenueCat section.

16 October 2026: version 1.1.0 also records how many times the parent corner was opened and how many times the app asked Apple to show its rating window, with the occasion and the time. The rating itself never reaches us. Both are described in the RevenueCat section.
