Terms and conditions
Last updated: 2026-09-15
The current "no-signup, local-only" version of captrice.io is NOT a commercial offerring, and comes without any guarantees or warranties.
Your data is completely owned by you—it's persisted in your browser's IndexedDB and never leaves your computer by itself. It's recommended to take regular backups using the backup/restore functionality provided in on the settings page store them safely. Your data is your own risk.
The content available in the Library section of the site could be derived from the work of others. Examples:
- Guitar tablature/music notation for a piece of music belonging to an artist
- Guitar tablature/music notation for guitar lesson shared by a content creator on platforms such as Youtube, Instagram etc.
Captrice does not claim ownership of the original music. The website tries to give attribution to the original artist/content creator where applicable. No copyright infringement is intended. Please reach out to show email in case of any objections.
The Teacher's edition of Captrice is in closed beta at present and the terms of use specific to it are shared privately with the teachers participating in the beta program for now. They will be made public once it's out of beta.
Privacy policy
Last updated: 2026-09-21
Data controller: Vineet Naik (vineet@captrice.io) is the data controller for any personal data referenced in this policy.
The website (www.captrice.io) and the app (app.captrice.io) don't collect user data or set cookies at all. All data is persisted in your browser and never leaves your computer by itself. Because this data is never transmitted to us, we have no access to it, no ability to view, copy, or recover it, and no basis on which to process it under GDPR. In other words, you remain fully in control of your data on your own device.
Your rights over this local data: since we never hold it, there's nothing for us to provide, correct, or delete on your behalf. You can export, back up, or permanently erase it at any time using the backup/restore functionality on the settings page, or by clearing your browser's site data.
Third party tools and services
Captrice relies on some third party tools and services, so it's important to know the following:
- Buttondown
- If you voluntarily signup for the newsletter subscription, your email address is collected via buttondown. Legal basis: your consent. You can unsubscribe at any time via the link in any newsletter email which removes your address from Buttondown.
- Umami
- Umami is used for traffic and visitor analytics. All visitor data is anonymized and no cookies are used. Legal basis: legitimate interest in understanding site usage, balanced against minimal privacy impact since no personal identifiers are collected.
- YouTube
- When you add a YouTube URL to a collection or exercise, the video is displayed using YouTube's embedded player (an iframe) hosted on YouTube's own domain. As a result, YouTube/Google may set cookies and collect data in your browser according to their own policies — these cookies are set directly by Google, not by Captrice, and are governed by Google's Privacy Policy. Captrice does not control what data YouTube collects through the embedded player.
Teacher's edition (closed beta)
The teacher's edition of Captrice is currently in closed beta, where teachers share their own course material with us directly and we help them turn it into structured exercises inside Captrice and generate a private bundle code for their students. Here's what that means in practice:
- What we collect: the material you send us (documents, notes, links, or similar), along with your email address and any details you share about how you'd like it structured.
- Legal basis: performance of the beta arrangement you've entered into with me, and consent for email contact.
- What it's used for: building your exercises and bundle code. Email address is only used for reaching out to you regarding the beta program. We don't use your material for anything beyond that.
- Who sees it: just me. It isn't sold, shared with third parties, or used to train anything, and it isn't shown to any teacher or student other than the ones you choose to give your bundle code to.
- Ownership: it's still your material. Sharing it with us to build your bundle doesn't give us any rights to it.
- How long we keep it: for as long as your bundle is active, or until you ask us to remove it by sending an email from your registered email address. Then we deactivate the bundle and delete your material completely.
Your Rights (GDPR)
Where we do hold limited personal data (newsletter email, or teacher's-edition material), you have the right to:
- Request access to, or a copy of, the data we hold about you
- Request correction or deletion of that data
- Withdraw consent at any time (e.g. unsubscribing)
- Object to processing based on legitimate interest
- Lodge a complaint with your local data protection supervisory authority
