Privacy policy

In short

Your videos and the audio files Tonify makes stay on your iPhone: the app has no way to upload them. There is no advertising identifier, no ads, no cross-app tracking and no account. The app does send a small amount of anonymous, technical information, and this page lists all of it.

Photos and Files

The app never asks for access to your photo library. iOS's own picker hands over only the single file you choose, and that file is copied into the app's own storage so it can be read. Files you convert are written to the app's Documents folder, which appears in the Files app under On My iPhone › Tonify.

Links you paste

The “From a link” option is the only place Tonify uses the network for your content, and only when you use it. The app requests exactly the address you paste — first a HEAD request to learn the file's type and size, then the file itself. The address is not logged and is not part of any data we receive. Tonify refuses links from YouTube, TikTok, Instagram and similar services: their terms do not permit downloading, and neither does the App Store.

Anonymous device record

On first launch the app signs in anonymously with Google Firebase, which gives it a random ID with no name, email or phone number attached. Under that ID we keep: your language and region setting, the app version, whether you have Pro, the use you picked on the first screen, when the app was first and last opened, and a few counters (onboarding finished, demo tried, number of conversions). Firebase Remote Config is also used to load settings we can change without shipping an update.

Usage events

When a conversion, ringtone, cut or demo finishes, fails or is cancelled, the app sends a short record to our server at tonify.app: the kind of job, the result and, if it failed, an error code; the format, bitrate and length of the output; where the file came from (Photos, Files, a link, the Share sheet or the Library) and its size; how long it took. It is sent together with the anonymous ID, your device model, iOS version, app version, language and whether you have Pro. It never contains file names, links or the contents of your files. We use it to find and fix what breaks and to see which features are used.

Subscriptions

Purchases go through Apple. To know whether your subscription is active we use RevenueCat, which receives an anonymous user ID generated on your device, your purchase history and the country of your App Store account. We also attach a few non-personal facts: the use you picked on the first screen, whether you tried the demo, and which version of the purchase screen you saw. If you installed Tonify after tapping an Apple Search Ads ad, Apple's attribution token (AdServices) is passed to RevenueCat so we can tell which campaign worked; Apple designs it to contain no user or device identifier, and it needs no tracking permission. None of this is used for advertising profiles or sold.

The contact form

If you write to us through tonify.app, we store your message, the name and email you type, your language, a hashed form of your IP address for rate limiting, and your browser's user-agent string. The app's Contact support screen sends the same kind of message, without a name, plus — only if you leave “Include device details” on — the app version, iOS version, device model and whether you have Pro. The exact line is shown on the screen before you send. We keep messages until the question is resolved and use them for nothing else.

The log on your device

The app also writes a detailed technical log of each conversion — settings, timings, error messages. It stays on your device and is sent only if you choose to share it with us. It never contains the contents of your files.

Who processes the data

Google Firebase (anonymous sign-in, device record, settings), RevenueCat (subscriptions), Cloudflare (hosts tonify.app and our server) and Apple (purchases). They may process data outside your country. We do not sell data, and nothing is shared with advertisers or data brokers.

Children

Tonify is not directed at children and does not knowingly collect personal information from anyone.

Your rights

You can ask us what we hold and have it deleted: email yaysoftltd+mp3_converter@gmail.com. Because the records are anonymous, write from the app's Contact support screen if you can — it lets us find them. Deleting the app removes the anonymous ID from your device, and nothing new is recorded after that.

Changes

If this policy changes in a way that matters, the date below changes with it.
