Privacy at audiogram.video
The short version
The video is drawn and encoded by your own browser, so your recording, cover art and photos are not sent to us. The single exception is captions from speech, which you start yourself and which sends only the chosen clip’s sound to be written out. Beyond that we receive some visit statistics you can switch off, feedback if you choose to give it, and error reports when our code breaks.
Your recordings and pictures
When you open a file, it is read from your device by this page. Decoding the sound, measuring it, drawing every frame and encoding the MP4 all happen in your browser tab. There is no upload step and no server that could receive the file to make your video.
Captions from speech
Captions are optional. When you press Make captions, the sound of the clip you selected on the timeline (not the rest of the recording, and never your pictures, title or other settings) is compressed in your browser and sent to be written out. Typing the words yourself, or opening an SRT or VTT file, sends nothing.
- What is sent. Only when you ask for captions from speech: the sound of the clip you chose, mixed to one channel and compressed to speech quality, and the language if you picked one. It goes from audiogram.video’s server to DeepInfra, a US company that runs the Whisper speech-recognition model, which sends back the words and their timings. Your IP address, the pictures, the file name and anything else in your project are not passed on.
- Nothing is kept. Our server passes the audio straight on and stores neither the audio nor the words. DeepInfra says it holds what it is sent in memory only while it works on the request, does not store it on disk, does not log its content and does not use it to train models (DeepInfra’s data-privacy notes, its privacy policy). The captions you get back stay in your browser.
- Bot check. Before the first request, Cloudflare Turnstile checks that it comes from a person. It looks at signals from your browser, sets no cookies and is not used for advertising (Turnstile privacy addendum).
- Limits and logs. To stop abuse, we count how many seconds of audio each connection and each short session sends per day. These counters use a one-way fingerprint of your IP address and are deleted after two days. Our logs record the length, the language and the outcome of each request, never the audio or the words.
- Legal basis. Making the captions you asked for (UK GDPR and GDPR Article 6(1)(b) and (f)); the limits and bot check protect the service (Article 6(1)(f), legitimate interests). Only send recordings you are happy to leave your device, and take care with other people’s voices.
What this browser keeps
- Your audiograms. Each project (its settings, captions, and copies of the recording, cover art and background photo) is saved in this site’s storage in your browser (IndexedDB and the origin private file system), so a reload or a closed tab doesn’t lose your work and your projects page can list them. Older projects are cleared automatically when space runs short, and you can delete any of them from that page.
- My styles, the looks you save by name, in local storage
(
audiogram:styles). - Small settings, such as your light or dark theme, whether you’ve seen the
studio’s first-run tips, and when you last answered the feedback card
(
vt-feedback).
None of this is sent to us. Clearing this site’s data in your browser settings removes all of it.
Converting unusual formats
If your browser can’t read a file directly (WMA, AIFF or AMR, for example), the page fetches the open-source ffmpeg.wasm converter, roughly 10 MB, from audiogram.video itself and converts the file on your device. It is only downloaded when a file needs it, and your recording is not part of that download.
Hosting
Cloudflare serves this site. To deliver pages and block attacks, its servers handle the usual connection details: your IP address, browser and the address you asked for. We rely on this only to keep the site running and secure (legitimate interests, UK GDPR Art. 6(1)(f)); Cloudflare’s privacy policy describes how it treats those logs.
Feedback and error reports
Once a video has been downloaded or shared, a little card can pop up asking you to rate audiogram.video out of five. Closing it is fine. With four or five stars we thank you and offer a link to review the site on Trustpilot (an independent company; following the link sends them nothing from us) or to share it. With one to three stars you can choose a reason and, if you like, write a note; please keep personal details out of it.
An answer is stored with: the stars, reason and note, whether you clicked to review or share,
what led to the card, the page path (with project ids masked), the site version, a
two-letter country code from the connection, your browser and operating system families,
and whether you were on a phone, tablet or computer. Your IP address is used briefly to stop
abuse and then discarded; no cookie or identifier is attached, and nothing from your
recording is included. Answers are deleted within 24 months. Your browser remembers in
vt-feedback when you last rated or closed the card (it stays away for 180 days
after a rating, 21 after closing, and for good after three closes). Google Analytics also
receives the star count and chosen reason, never the note.
If our code fails unexpectedly, your browser sends a technical report: the error, where in
our scripts it happened, the page path, site version, a one-off id for that page view,
browser, system, device type and country. Addresses are shortened and anything that looks
like an email address or a file name is removed before it’s sent, and it never contains your
recording, captions or anything you typed. Individual reports are deleted after 30 days; a
summary of each problem is kept until 180 days after it last occurred. Google Analytics
receives a single js_error event naming only the error type.
We store feedback and error reports on Cloudflare (Workers and Durable Objects), acting for us. The legal basis is our legitimate interest in keeping the studio working and improving it, and for a note, your choice to send it. To object or have something deleted, see “Your rights”.
Visit statistics
Cloudflare Web Analytics and Ahrefs Web Analytics count visits without cookies and give us totals only: page views, where visitors came from, rough country and device type.
Google Analytics 4 shows us which templates, guides and controls are worth keeping. It records the pages you view and studio actions such as opening a recording, picking a template, making captions or exporting, with rounded values like the clip’s length band, linked by a random id in a first-party cookie. It never receives your audio, file names, titles or caption text. Advertising features and Google signals are off. Google processes this data under its privacy policy and its notes on partner sites. Data that goes to the US is covered by the EU-US Data Privacy Framework, and each event is erased 14 months after it is recorded.
We rely on legitimate interests (UK GDPR Art. 6(1)(f)): knowing which templates and guides help is how audiogram.video gets better. Since the Data (Use and Access) Act 2025, the UK’s Privacy and Electronic Communications Regulations let a site set a cookie like this for statistics. Saying no takes one click; the next section shows where.
Cookies, and switching them off
There’s no advertising here. The only cookies are Google Analytics’ _ga and
_ga_*, which last up to two years, and a short notice mentions them on your
first visit. To object, open Cookie settings in the footer and choose
Turn off analytics; this browser will remember. A
Global Privacy Control signal does the same,
and then the cookies are never set. We don’t sell personal data.
Who runs audiogram.video
An independent, self-funded project with no accounts. We keep no profile of you. What we hold is feedback answers and error reports, neither of which carries a name, cookie or identifier, and the short-lived counters that keep captions within their limits.
Your rights
Depending on where you live, you may have the right to access, correct or delete personal data, to restrict or object to its use, to take it elsewhere, and to complain to a supervisory authority. Your projects live only in your browser, so clearing this site’s storage is how those rights apply to them. Analytics can be switched off in Cookie settings; your Google Account has further options of Google’s own. Ratings and error reports are anonymous, so if you want one deleted, describe it (about when, and what it said) and we will find it. Write to hello@audiogram.video about anything on this page; the contact page has more.
Changes
Any new use of data on audiogram.video will be described here first, with a fresh date at the top of the page.
