This is the page where we explain what data Slice Studio collects, why we collect it, and what you can do about it. We've tried to write it in plain English. If anything is unclear, email us at mediabyslice@gmail.com and we'll fix it.
The short version: we collect the data we need to make our tools work, we don't sell it to anyone, and you can ask us to delete it at any time.
Who we are
Slice Studio is a product of ADIM LTD, a private limited company registered in England and Wales (company number 16599511). We build small tools for podcasters and the people who edit them. ADIM LTD is the data controller for the personal data described in this policy.
Registered office: 121, 1 Didsbury Gate, Houseman Crescent, Manchester, M20 2JP, United Kingdom.
Contact: mediabyslice@gmail.com.
What we collect
There are four buckets:
- Account data. Your email address, name, and (if you sign in with Google) your profile picture. We only see what Google chooses to share with us: name, email, and profile photo. We don't ask for anything else.
- Content you upload. Audio files, video clips, transcripts, captions, images, links, and any text you type into our tools. This is yours; we just store it for you so the tools work.
- Usage data. Pages you visit on our site, buttons you click, the approximate country we guess from your browser's timezone, the browser and device you're using, and how you arrived (referrer, UTM tags). We use this to figure out what's working and what isn't.
- Payment data. If you pay for a plan, Stripe handles your card details. We never see the card number. We only see the subscription status and the email tied to the customer record.
Why we collect it
Different data, different reasons:
- To make the product work. Without an account we can't save your projects. Without your uploads we can't transcribe or render captions. (Legal basis: performance of contract.)
- To improve the product. We look at aggregate usage to see what's popular and what's broken. We never sell this data or share it with advertisers. (Legal basis: legitimate interest.)
- To send you the emails you signed up for. Mostly product updates and things you've explicitly requested. You can unsubscribe any time. (Legal basis: consent.)
- To comply with the law. Tax records, payment receipts, that kind of thing. (Legal basis: legal obligation.)
Who we share it with
We use a small number of trusted services to actually run the product. Each one handles a specific job. They process your data on our behalf, under contract.
- Supabase: database, authentication, file storage (servers in EU-West-2, London).
- Netlify: website hosting and content delivery.
- Stripe: payment processing.
- Google: only if you choose to sign in with Google (OAuth).
- Anthropic, OpenAI: AI generation for captions, talking points, greetings, and similar features. Inputs are not used to train their models.
- AssemblyAI: transcription of audio you upload.
- Resend: sending transactional emails (password resets, share notifications, transcripts you ask us to email).
- Fly.io: running our caption-rendering worker.
We do not sell your data. Ever. Not to advertisers, not to data brokers, not to anyone.
Where the data lives
Most of your data is stored on servers in the UK / EU (Supabase EU-West-2, London). Some processors (Stripe, Google, Anthropic, OpenAI, AssemblyAI, Resend) operate from the United States. When data moves outside the UK / EU, we rely on the UK International Data Transfer Addendum or Standard Contractual Clauses (SCCs) approved by the European Commission.
How long we keep it
- Active accounts: for as long as you keep using Slice Studio.
- Recordings you upload: once a project has gone 90 days with no exports and no edits, we email you and then delete the original recording. The captions, clips and exports you made from it stay. A project you're still working on, or one you never got an export out of, keeps its recording.
- Inactive accounts: after 24 months of no activity we'll email you, and if we don't hear back we delete the account and its content.
- Deleted accounts: we delete the data within 30 days, except for invoices and tax records which UK law requires us to keep for six years.
- Backups: deleted data persists in encrypted backups for up to 30 days before being purged.
- Analytics: aggregated, anonymised analytics may be kept indefinitely.
Making clips with Slice in ChatGPT and Claude
The clip tools in ChatGPT and Claude work on your own Slice account, so the first time you use one you sign in to Slice and approve the connection. Here is what that involves.
What we receive
- The video you attach in the chat, or upload through the link we give you. For an attached file, ChatGPT gives us a temporary link to it.
- What you ask the tools to do: which clips to make, caption styles, sizes and positions, a title, or a topic to look for. We don't receive the rest of your conversation, your chat history or memory.
- A sign-in token that lets ChatGPT or Claude act on your Slice clips. They never see your password. We store tokens only as scrambled (hashed) values; an access token lasts an hour and a refresh token 30 days.
What happens to it
- The video and the clips made from it are stored in your Slice account, exactly like videos you upload on the website, and the rest of this policy applies to them: private storage, the 90-day clearing of unused recordings, and deletion with your account.
- AssemblyAI transcribes the video so clips can be found and captioned. Fly.io runs the server ChatGPT and Claude talk to and renders the clips. Supabase stores your projects.
Disconnecting
Remove Slice in ChatGPT's or Claude's settings to stop it acting for you, or email mediabyslice@gmail.com and we'll revoke the connection. Deleting a clip or your account on the website deletes it everywhere.
The Slice transcription tool in ChatGPT and Claude
You can use Slice inside ChatGPT or Claude to turn an audio or video file into text. You don't need a Slice account for it. Here is exactly what happens to your data when you do.
What we receive
- The audio or video file you attach, or the link to a file you give it. For an attached file, ChatGPT gives us a temporary link to it.
- An anonymous ID for you, so we can apply the daily limit. In ChatGPT this is the anonymised user ID that ChatGPT sends to every app for rate limiting; it is not your name or email and we can't use it to find out who you are. In Claude, or anywhere that doesn't send one, we use a random connection ID we create ourselves, or your IP address if there is nothing else. We only store a scrambled (hashed) version of these, never the original.
- An email address, only if you ask for the transcript to be emailed and give us the address.
Why
- The file or link: to make the transcript you asked for.
- The anonymous ID: to limit how many files each person can transcribe a day, so the tool stays available for everyone.
- The email address: to send you that one email. We don't keep the address, and it isn't added to any mailing list.
Who handles it
- AssemblyAI fetches the file and turns the speech into text, on our behalf.
- Supabase stores the finished transcript for us.
- Resend sends the email, if you asked for one.
- Fly.io runs the server that ChatGPT and Claude talk to.
How long we keep it
- We don't store a copy of your audio or video. AssemblyAI reads it directly to make the transcript.
- The transcript, its subtitle files and the link you gave are deleted after 30 days, from our storage and from AssemblyAI.
- After that we keep a small record with no content in it: how long the file was, what it cost us to process, when, and the scrambled ID, so we can keep the daily limits and our costs straight.
Deleting it sooner
Every transcript comes with a link to its own page. Anyone with that link can read the transcript, so only share it with people you want to see it. That page has a “Delete this transcript” button that removes it from Slice straight away, and from AssemblyAI within a day. You can also email mediabyslice@gmail.com with the link and we'll delete it for you.
Your rights
If you're in the UK, EU, EEA, or California, you have specific rights over your personal data. You can:
- Ask for a copy of the data we hold about you.
- Correct anything that's wrong.
- Delete your account and the data tied to it.
- Object to processing, or restrict it.
- Receive your data in a portable format (JSON).
- Withdraw consent for any processing based on consent.
- Complain to a supervisory authority (ICO in the UK, your local DPA in the EU).
To exercise any of these rights, email mediabyslice@gmail.com. We'll respond within 30 days, usually faster.
Cookies and tracking
We use the minimum number of cookies we can get away with:
- Essential cookies: to keep you signed in. Can't be turned off without breaking the product.
- First-party analytics: to count page visits and feature usage. No third-party trackers, no advertising pixels.
We don't use Google Analytics, Facebook Pixel, or any tracker that follows you around the internet.
Children
Slice Studio is not intended for anyone under 13. If you believe a child has signed up, email us and we'll delete the account.
Security
We do the standard stuff: encryption in transit (HTTPS everywhere), encryption at rest for stored content, hashed passwords, access controls inside the team. No system is bulletproof, but we take it seriously.
If you spot a security issue, please email mediabyslice@gmail.com rather than posting it publicly.
When this policy changes
When we make material changes, we'll update the "Last updated" date at the top and, where the change affects you directly, send you an email. Small wording tweaks won't get an email.
