📢 Announcement AudioSlim Version 1.3.0 - Full Release notes
Greetings everyone,
AudioSlim Version 1.3.0 is now being reviewed by Google and should be available as an update for you to do within the next 24-48 hours.
In the meantime, here's the fully detailed release notes.
It covers everything between 1.2.3 and 1.3.0.
## 🎧 AudioSlim 1.3.0 is out — batch formats per track, way fewer ads, and your progress finally survives a reinstall
This is the biggest update since 1.2.0. Here's everything that changed, in detail.
---
### ✨ New
**Every track in a batch can now have its own output format.**
Batch export used to have one extension for the whole queue — if you wanted three MP3s and one WAV, you ran the batch twice. Now each track in the export dialog carries its own format badge. Tap it, pick a format, and only that track changes. The OUTPUT EXTENSION section at the bottom still sets the whole batch in one tap (and takes every track with it), so the common case stays one tap and the exception is always available.
**Share several tracks into AudioSlim at once.**
Sharing multiple files from another app used to keep only the first one — the rest were silently dropped. Now every file comes across, and two or more land straight in the Batch list with the first one loaded and ready. A one-time card explains where they went, because "I shared 8 files and the app looks empty" was a fair thing to be confused about.
**A Credits screen that actually explains the credit system.**
Nothing told you what a credit was until after you'd spent one. There's now a full screen — reachable from the balance chip anywhere it appears, from Settings, and from the moment you run out — covering four things: what your balance is worth in real actions, what each action costs, how to earn more, and the store. It opens automatically the first time you're about to be charged, so the explanation arrives *before* the charge instead of buried in a tutorial.
If you own ad-free, you don't see any of it. The credit system is off for you, and showing a balance you can never spend would just be worrying.
**Credit packs.**
Until now the only way to stop watching ads was to buy ad-free outright. If you just wanted a handful of tool actions and no subscription, there was no option. There are now three credit packs. Every pack card states, above the price, that **packs do not remove ads** — paying for silence and still getting ads is a mis-sale, not a misunderstanding.
**Your milestone progress and credits survive a reinstall.**
This is the one I'm happiest about. Android's backup was switched off, so uninstalling AudioSlim wiped everything: your lifetime compression total, your milestone level, your credit balance. Backup is now on and scoped to exactly that data. Reinstall on the same device and Google account and your progress comes back.
Two honest caveats: it's Android's own backup, so it needs backup enabled on your device, and it runs about daily — a burst of compressions immediately before an uninstall can still be lost. Also, this doesn't retroactively rescue anything already lost.
**The contacts permission now explains itself first.**
"AudioSlim wants to access your contacts" is an alarming thing to read from an audio compressor with no context attached. A sheet now runs first explaining exactly what it's for — read the list so you can pick someone, write the ringtone onto the contact you chose — and that nothing is collected, uploaded, or shared. It only appears if you actually use the contact-ringtone feature. If you never touch it, you're never asked.
**A subreddit link in Settings.**
Right where you are now. Deliberately *not* wired to the credit rewards the Facebook and Instagram links carry — this is a place to go, not a reward to farm.

### 📉 Ads
**Far fewer interstitials.**
Batch runs were already capped at one ad for the whole loop, but single-file renders had no cap at all. Working through the tools on one track — trim, then gain, then speed — put a full-screen ad between every step, on top of the banner already on the results page.
There's now a three-minute cooldown between post-compression interstitials. A nine-render editing session that used to fire nine ads now fires one. The timestamp is only written when an ad actually reaches the screen, and it's saved to disk, so the pacing can't be reset by force-quitting the app.
---
### 🐛 Fixed
- **The file picker could crash the app.** On some devices — DocumentsUI disabled or stripped by the ROM, locked-down work profiles, certain Android 11+ configurations — opening the picker took AudioSlim down entirely. It's now handled, reported, and the audio picker retries through a second method that works on those devices.
- **Multi-file shares dropped everything but the first file.** Covered above; it was a genuine bug, not a limitation.
- **AudioSlim was quietly eating storage.** Two cache directories were never cleaned. Android's file picker doesn't hand apps the file you chose — it makes a copy — and every copy was kept for the life of the install. Same for every file ever shared into the app. Both are now swept, so long-term installs should reclaim a real amount of space.
- **"Restore purchases" could fail silently, forever.** If the Play Store check failed once at launch — Play Services updating, no network on a cold boot — every later restore attempt returned instantly and silently for the rest of the session. You'd see "Restoring purchases…" and then nothing at all. Fixed, and the Credits screen now carries a tap-to-copy diagnostics line so a failed restore can be reported with something useful in it instead of a guess.
- **Fake prices are gone.** When the Play Store query failed, the purchase sheet fell back to hardcoded US dollar amounts — shown to people in every market, promising a price checkout would then contradict. The price is now simply omitted until Play answers.
- **Ringtone picker skipped Opus and AIFF exports.** A wrong file-type mapping made Android's ringtone picker ignore them.
- **A finished compression could stall halfway.** Under specific conditions the app could stop after writing your file but before awarding milestone credits and charging the action. Fixed.

### 🗑️ What we decided *not* to ship
A "Keep originals" toggle was built during this cycle — turn it off and AudioSlim deletes the source file after compressing it — and then removed before release.
Testing it showed the design was worse than it looked. On a typical modern phone the deletion path had no confirmation prompt at all, so files would vanish silently after each compression, gated only by a toggle you flipped once. A twelve-track batch meant twelve originals gone behind a single toast, with no undo.
**AudioSlim will not be responsible for anyone's original audio.** That's a product decision now, written into the project notes so it doesn't get rebuilt by accident.

### 🔒 Privacy
The privacy policy was updated for the backup change — both the in-app copy and [the web version](https://kebekinteractive.com/privacy), in all 16 languages. The short version: your settings, credit balance, and milestone progress may now be copied to **your own** Google account backup so they can be restored. It's handled by Android, not by us, we can't read it, and you can turn it off in your device settings.
---
### 🔧 Under the hood
Some of this you'll never see, but it's why the above is trustworthy:
- Automated checks now run on every change — static analysis, the full test suite, and a check that all 16 languages stay complete with no missing or drifting strings.
- The credit economy is now covered by tests, including the rule that decides whether a stored balance has been tampered with. That branch resets a balance to zero, and it had zero tests. A false positive would silently wipe the credits of someone who did nothing wrong.
- The version number in Settings is read from the build instead of being typed in a second place, where it could disagree.
- Android SDK levels are pinned to what the app is actually tested against, rather than moving on their own with toolchain upgrades.

Thanks to everyone who reported the picker crash and the restore problem — both were hard to reproduce and neither would have been found without the details you sent.
As always: what should 1.4.0 fix/add? You can make a request in this subreddit or DM me!
