Privacy Policy
Last updated 28 July 2026 · Charles-Antoine Pouliot
ChordViz collects as little as it can get away with. This page lists everything the app and this website send or store, and who processes it.
The short version
Your audio, your MIDI, and the layouts you build never leave your computer. ChordViz processes everything locally. It makes exactly three kinds of network request: starting your trial, checking your licence, and looking for updates. Nothing else is transmitted.
What the desktop app sends
- Trial check. On first launch ChordViz sends a salted, one-way SHA-256 hash of a device identifier to our trial service, which records when your 7-day trial started. The hash cannot be reversed into your hardware ID, and it is not linked to your name or email. It exists so the trial can be offered once per machine.
- Licence activation. When you enter a licence key, ChordViz sends that key and a device identifier to Lemon Squeezy to activate, validate, or deactivate the device slot. This is what lets you see and manage your devices from your account.
- Update check. ChordViz fetches an update feed from our download host to see whether a newer version exists. As with any web request, our host sees your IP address.
ChordViz contains no analytics, no telemetry, no crash reporting, and no advertising SDKs. It does not track how you use the application.
What this website collects
- Account. If you create an account, we store your email address and authentication details through Clerk. We use your verified email to find the orders and licences that belong to you.
- Purchases. Checkout is handled by Lemon Squeezy as merchant of record. They collect your payment and billing details; we never see or store your card information. We read your order history and licence keys from them to display your account page.
- Mailing list. If you submit your email for launch updates, it is stored with Resend and used only to email you about ChordViz. Every email includes an unsubscribe link.
- Hosting logs. Our host, Vercel, keeps standard request logs (IP address, user agent, requested URL) for security and reliability.
We do not use advertising or cross-site tracking cookies. Cookies set on this site are the ones Clerk needs to keep you signed in.
Processors we use
- Lemon Squeezy — payments, tax, licence keys (merchant of record)
- Clerk — account sign-in
- Supabase — trial records (device hashes only)
- Resend — mailing list
- Vercel and Cloudflare R2 — website hosting and installer downloads
We do not sell your personal information, and we do not share it with anyone beyond the processors above.
How long we keep it
Order and licence records are kept as long as your licence is valid, since a perpetual licence needs a lasting record. Trial hashes are kept so a trial can’t be restarted on the same machine. Mailing-list entries are removed when you unsubscribe. Account data is deleted when you delete your account.
Your rights
You can ask us for a copy of the personal data we hold about you, ask us to correct it, or ask us to delete it — including your account and your place on the mailing list. Email charles@chordlab.ca and we will action it. Depending on where you live, you may also have the right to complain to a data protection authority.
Children
ChordViz is not directed at children under 13, and we do not knowingly collect their personal information.
Changes
If this policy changes, the “last updated” date above changes with it. See also our Terms & License.
