This privacy policy explains what Aito Ventures Pte. Ltd. (“we”, “us”) does with your information when you use our Detune iPhone apps — Detune: Learn Music Production and Detune: Learn Music Theory (each an “app”, together the “apps”) — or visit getdetune.com (together, the “Services”). Both apps are built the same way and handle data the same way; where something applies to only one of them, we say which. If you have a question, email privacy@getdetune.com.

The short version

The Detune apps have no accounts. You never give us your name, email or password to use them.
Your lessons, progress, streaks and settings are stored on your device.
Each app sends anonymous usage analytics to PostHog, hosted in the EU, so we can see which lessons work and where people get stuck. This is tied to a random identifier for your installation, not to you.
Purchases go through Apple. To recognise a subscription we use RevenueCat, which receives an anonymous app identifier and your App Store transaction details, never your name or payment card.
getdetune.com measures its own traffic with PostHog, also in the EU, and without cookies: nothing is stored on your device and no identifier follows you between visits or between the website and the apps.
We do not run advertising and we do not track you across other apps or websites.
If you email us, we keep the email to answer you.

What the apps store on your device

An app keeps the following on your iPhone. The full data stays on your device; only the summary described under “Usage analytics” below leaves it.

Your learning progress: which lessons you completed, hearts, streaks, XP and level.
Your answers to the short onboarding quiz, which personalise your plan.
Settings such as your daily-reminder hour.
Synth patches you create (Detune: Learn Music Production only — Learn Music Theory has no synth).

Each app stores its own copy of this, and deleting an app deletes the data it holds. It is included in your iPhone backups according to your iOS settings.

Usage analytics

To understand how the apps are used and to improve the lessons, each app sends usage events to PostHog (PostHog, Inc., USA). We use PostHog’s EU cloud, so this data is stored on servers in the European Union.

When you first open an app it generates a random identifier for that installation. This identifier is not your name, email, Apple ID or advertising identifier, and we cannot use it to work out who you are. The following is recorded against it:

What you do in the app: which lessons, tutorials and screens you open, whether you answer exercises correctly, when you complete or leave a lesson, streak and XP milestones, and — in Learn Music Production — what you do in the Studio (for example adding a track or an effect, but not the music you make).
Your answers to the onboarding quiz and the learning path you are on.
Paywall and subscription events: seeing the paywall, starting or cancelling a purchase, and whether a subscription or trial is active. Prices and product names are included; payment details never are.
Errors the app runs into, such as a failed purchase or a file that could not be imported.
Technical information: device model, iOS version, app version, language, time zone and screen size. PostHog derives an approximate location (country and city) from your IP address when it receives an event; the address itself is not kept as part of your profile.

We do not use this data for advertising, we do not sell it, and we do not combine it with data from other apps or websites. It is not used to track you in the sense of Apple’s App Tracking Transparency framework, so neither app ever asks for tracking permission.

PostHog processes this data on our behalf under a data-processing agreement. See PostHog’s privacy policy. Because PostHog, Inc. is a US company, its staff may in limited cases access data stored in the EU from the United States; those transfers are covered by the EU standard contractual clauses in our agreement with PostHog.

We keep analytics data for as long as it is useful for understanding how the apps are used, and we delete it when it no longer is. If you would like the analytics data for an installation deleted, email privacy@getdetune.com and say which app. Deleting the app stops any further collection.

Subscriptions and purchases

Pro subscriptions are sold and billed by Apple through the App Store under Apple’s terms and privacy policy. Each app sells its own subscription, and we never see your payment card.

To check whether your subscription is active, the apps use RevenueCat (RevenueCat, Inc., USA). RevenueCat receives:

a random identifier the app generates for your installation,
your App Store transaction and subscription status (product, dates, renewal state),
basic device information such as iOS version, app version, locale and country.

RevenueCat processes this on our behalf to unlock Pro, to restore purchases on a new device, and to give us aggregate subscription statistics. See RevenueCat’s privacy policy. Subscription records are kept for as long as needed for accounting and tax obligations.

An app also tells PostHog whether your subscription or trial is active, under the same random installation identifier, so we can see how the paywall and trial are working. See “Usage analytics” above.

Notifications

If you turn on the daily reminder or the trial-ending reminder, the app schedules a local notification on your device. No notification data leaves your phone.

Support email

When you write to us, we receive your email address and whatever you include in the message. We use it only to reply and to improve the apps, and we keep the correspondence for up to two years.

This website

getdetune.com is a static site served by Cloudflare. Cloudflare processes connection data such as your IP address to deliver the pages and protect against abuse, under Cloudflare’s privacy policy. The site sets no cookies.

To see which pages are read and which links are used, the site sends usage events to PostHog, on the same EU cloud the apps use but into a separate project that holds website data only. It runs in PostHog’s cookieless mode:

Nothing is stored on your device — no cookies, no localStorage identifier, no persistent visitor id. Closing the tab ends it.
Instead of an identifier, PostHog derives a visitor hash on its servers that rotates daily, so repeat visits within a day can be counted without you being recognised tomorrow or across other sites.
Your IP address is not stored on the event. Because that also stops PostHog’s location lookup, the site asks Cloudflare’s edge for your country only — two letters, nothing narrower — and attaches that.
We record page views, how long a page was open, clicks on App Store links, Serum skin downloads, whether the synth on the home page was played, and, while an offer-code page such as /reddit is running a live offer, the steps taken on it. Each event carries the page path, the country, and basic technical information such as device type, browser and referrer.
There is no session recording, no heatmap, no autocapture of every click, and no advertising or cross-site tracking. Nothing here is linked to your use of the Detune apps, or to you.

Because nothing is stored on your device and nothing identifies you, this needs no cookie banner and no consent under the ePrivacy rules. If you would still rather not be counted, the site honours your browser’s Do Not Track and Global Privacy Control settings, and any content blocker that blocks PostHog will stop the events without affecting the page.

Children

The Detune apps are not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us with personal information, email us and we will delete it.

Your rights

Depending on where you live, you may have the right to access, correct, delete or export personal information we hold, to object to or restrict its processing, and to complain to a data-protection authority. Because the apps store your learning data on your device and we hold very little about you, most requests are met by deleting the app. To have your analytics data deleted, or for anything else, email privacy@getdetune.com and we will respond within 30 days.

We are established in Singapore and handle personal data under the Personal Data Protection Act 2012. For users in the European Economic Area and the United Kingdom, our legal basis for processing subscription data is performance of our contract with you; for usage analytics it is our legitimate interest in understanding and improving the apps, balanced by the fact that the data is pseudonymous, stored in the EU and never used for advertising; and for support email it is our legitimate interest in answering you.

Changes

We will update this page when our practices change and adjust the date at the top. Material changes will be announced in the apps.
