Privacy Policy

1. Who we are

Audionix is published by Sleeping Giant Marketing Services Private Limited ("we", "us"). You can reach us at hello@sleepingiantmarketing.com.

2. No accounts, no user data stored by us

Audionix does not require you to sign up, log in, or create an account of any kind. There is no Audionix user database — the app has nothing to store about you because it never asks who you are. The only service we run is a small purchase check (section 4) that answers a yes/no question and keeps no record of you.

3. Your music library

When you point Audionix at a folder on your device (on Android, the only platform with a local library at the moment), it reads the audio files in that folder to build your cassette library — titles, artists, durations, and embedded artwork. The scan itself happens entirely on-device, and your audio files are never uploaded anywhere. The one thing that does leave the device is the text-only metadata lookup described in section 4. Library data (which cassettes exist, their names, play state, and your settings) is stored locally on your device using standard on-device storage, and is removed if you uninstall the app.

4. What does talk to the internet

• Cover art & metadata lookup. To find matching artwork and correct track and album names, Audionix sends the title and artist (or album name) of tracks and cassettes in your library to the iTunes Search API — text only. The audio file itself, its location on your device, and any account, advertising ID or user ID are never sent, because the app has none. This happens automatically in the background while your library is scanned and whenever a cassette has no artwork, and again whenever you use "Fetch Metadata" or refresh a track or cassette online. It is a standard, unauthenticated public API call. You can switch the automatic lookups off at any time with "Auto online lookups" on the REAR tab; with it off, Audionix only contacts the iTunes Search API when you explicitly ask it to (Fetch Metadata, or refreshing a track or cassette online). The artwork image that comes back is then loaded from Apple's image servers, and, like any network request, Apple's servers can see your device's IP address.
• Internet radio. Audionix uses the public Radio Browser directory (radio-browser.info) for the Radio tab. When the app opens, it loads a station list for your device's region so stations from your country appear first, even if you never open the Radio tab; this sends your device's two-letter region code (for example "IN"), not your location. The directory also receives the station name you search for, and the ID of a station when you tune in (so it can count plays). Audio streams, and station logos, load directly from each station's own servers (some stations stream over unencrypted HTTP). Like any network request, these servers can see your device's IP address.
• Purchase check (Google Play). Audionix is a paid app, and each time it opens it checks that your Google account still owns it (for example, that the purchase wasn't refunded). It does this through Google's Play Integrity API: Google Play on your device returns an encrypted token, and the app forwards that token, plus a random one-time code, to a small service we run on Supabase. The service decrypts the token, reads whether Google says the app is licensed, and replies "licensed" or "not licensed". The request contains no name, email, advertising ID, library information or listening data, and we do not store the token or the reply against you. We keep only short-lived technical logs of the result label (for example "licensed") and error codes. Like any web service, our host (Supabase) also records standard request details, such as your device's IP address and the time, in its platform logs, which it keeps for a limited period (from about a day to a few weeks, depending on the plan). Google processes the integrity request under its own privacy terms. If the check can't finish — you're offline, the service is down, or Google can't evaluate your device — Audionix keeps working as normal. It only locks when Google Play explicitly reports that your account doesn't own the app; that result is remembered on your device so a refund stays in effect offline, and it clears as soon as Google Play reports the app as licensed again. A separate check that the app hasn't been modified or re-signed runs entirely on your device.
• Standard app-store & OS-level diagnostics. The platform you installed Audionix from (Apple App Store or Google Play) may collect basic, anonymized crash and install diagnostics under its own privacy terms. Audionix itself does not add any analytics, tracking, or advertising SDKs.

5. This website

This website (the home, support, privacy and terms pages) sets no cookies, runs no analytics, and loads no third-party scripts, fonts or trackers. Like any web server, our host keeps standard server logs, which is the only information recorded when you visit. If you email us, we use your message and email address only to reply to you.

6. Permissions Audionix asks for

• Storage / media access — to read the music folder you choose. On Android 13 and newer you pick the folder through the system picker, and Audionix does not request a broad storage permission; older versions of Android may ask for storage access instead. Either way, you choose the folder and Audionix never scans your whole device. Cover art you pick yourself is chosen through the system photo picker, which only shares the image you select.
• Network access — for internet radio, the online lookups, and the purchase check described in section 4.
• Audio & background playback — so music keeps playing when the app isn't in the foreground.
• Modify audio settings — so the 10-band EQ can use Android's built-in audio effects.
• Vibration — for the haptic feedback on the deck's keys.

Separately, the OPR/BATT indicator light on the deck reflects your battery level. This is not a permission, and the reading stays on your device.

7. What we don't do

• We don't collect your name or email through the app, and Audionix has no account, advertising ID or user ID.
• We don't sell data, and we don't build a database of our users. The only server we operate is the purchase check in section 4, which keeps no personal data. The only other parties the app contacts are the ones listed in section 4: Apple (iTunes Search), Radio Browser and the radio stations themselves, and Google Play.
• We don't run ads or ad-tracking SDKs.
• We don't build a profile of your listening habits.

8. Children's privacy

Audionix does not knowingly collect information from anyone, including children, because Audionix itself does not send personal information to us.

9. Your rights and deleting your data

All of the data Audionix keeps (your library, mixtapes, play state and settings) lives on your device. Uninstalling the app, or clearing its storage in your device settings, deletes it. Because we don't store any personal data about you (the purchase check keeps no record of you; see section 4), we hold no copy of your data and have nothing to delete on our side.

10. Changes to this policy

If this policy changes — for example, if a future feature adds a new network call — this page will be updated and the "last updated" date above will change accordingly.
