Privacy Policy
Last updated: September 5, 2026
Aback Audio processes audio entirely in your browser. This policy explains, in plain language, what that means for your data.
Aback Audio ("we", "our", or "us") operates abackaudio.com, a collection of free, browser-native audio utilities. Our core promise is simple: your audio stays on your device. This Privacy Policy explains the limited data this website handles and the controls you have over it.
All audio decoding, processing, and encoding happens inside your browser using Web Audio and local WASM codecs. We operate no audio-processing servers.
You can use every core tool without an account. We never receive filenames, waveforms, metadata, or audio content through the tools themselves.
Aback Audio is served as a static website from Cloudflare Pages. The servers only deliver HTML, CSS, JavaScript, and codec assets. They never accept your audio.
Open your browser's developer tools (Network tab) while processing a file: no request carries your audio bytes.
1. The short version
Aback Audio is a client-side utility platform. Files you choose are read, decoded, and encoded on your own device. Aback infrastructure does not receive your audio for normal tool execution, and we have deliberately built no upload pipeline, object storage, or processing queue.
If a tool fails, it fails locally. We never fall back to sending your file to a server.
2. Information we do not collect
Because processing is local, we do not collect:
- Your audio files or recordings
- Audio content, waveforms, PCM data, or hashes of your files
- File names, durations, or embedded metadata from files you process
- Your identity or an account for using core tools
3. Hosting, technical data & cookies
The site is delivered by Cloudflare Pages. Like any website, requests to load the page can produce standard technical data (such as IP address, browser type, and request time) handled by our hosting provider under its own privacy practices. We also use browser-local storage for a small number of preferences:
- aback_theme: your light/dark theme choice
- aback_locale: your preferred language
- aback_cookie_consent: your consent choice
These are stored only in your browser and can be cleared at any time.
4. Step-by-step local data flow
You select a file using the file picker or drag and drop.
The File object is read as an ArrayBuffer in your browser.
The buffer is decoded locally (Web Audio or a WAV parser).
PCM is processed and encoded locally with WASM codecs.
A Blob is created on your device and offered for download.
Temporary object URLs and buffers are released.
No step transmits your audio.
The only network requests that occur while a tool runs are loading the application's own static assets.
5. Advertising & analytics
Aback Audio is free and may display advertising. Advertisements are served by third-party networks in reserved areas of the page and never interact with the local processing engine.
- No filename, audio metadata, or audio content is shared with advertisers.
- Analytics, where present, is limited to coarse, non-identifying product events such as 'tool opened' or 'processing completed'.
- We never transmit audio-derived data, hashes, or fingerprints.
6. Security
Client-side processing does not make an application automatically secure. We treat every file as untrusted input and isolate work in the browser, validate formats before processing, cap work for very large files, and keep codec dependencies pinned and reviewed.
Please report suspected security issues through the contact page rather than public channels.
7. Children's privacy
The Service is a general-purpose utility and does not knowingly collect personal information from children. Since we do not collect audio or accounts, children's use of the tools does not result in personal data processing by us.
8. Your rights & choices
Because we hold none of your files, the most relevant controls are local ones: clear your browser's storage to remove saved preferences, and use your browser's private mode if you prefer no persistence. For any privacy question, contact us using the details below.
9. Policy updates
We may update this policy as the service evolves. Material changes will be reflected by an updated 'Last updated' date on this page. Continued use after changes constitutes acceptance of the revised policy.
10. Contact
For privacy questions or requests, reach out. We're happy to explain exactly how a tool works.

Privacy questions
Does Aback Audio upload my audio anywhere?
No. Every tool decodes, processes, and encodes on your device. There is no upload endpoint, no object storage, and no remote processing service.
Is this really private, or just marketing?
It is architectural: audio never leaves the browser because there is no backend to receive it. You can confirm this in your browser's network inspector while running any tool.
What data do you collect?
No audio, filenames, or metadata from files you process. The site relies on static hosting and limited local storage for preferences. Optional advertising/analytics only receive non-audio, non-identifying signals.
Can I use the tools without an account?
Yes. Core tools require no account, no login, and no payment.
Are files stored on Cloudflare or anywhere else?
Files are never transmitted to Cloudflare or any other server. Cloudflare Pages only delivers the static application and codec assets.
What happens if a local tool fails?
It fails gracefully with a clear message. There is no automatic 'server fallback'. We would never upload your file as a recovery path.
