Privacy Policy

Last updated: 20 September 2026

This Privacy Policy explains what information Try Convi ("we", "us") collects, how we use it, and the choices you have. By using tryconvi.com you agree to this policy.

Information we collect

• Email address. Only if you choose to give us one, and only for the thing you gave it for: either to be told when the app is ready, or to be reminded to practice. It is never required to use anything on the site, and we store it so that we can actually do what you asked rather than losing it the moment a send fails.
• Reminders, if you ask for them. If you turn on reminders after clearing a section, we keep one small record: a notification address from your browser or your email address, which language you were practicing, when your browser last opened the site, and how many reminders we have sent since. It is filed under a random identifier your own browser generates. There is no name and no account attached to it, and none of your practice progress is in it. We send at most four reminders before stopping on our own, and every one of them has a one-click way out that needs no login. That identifier is also what a reminder needs in order to know you have been away: while reminders are on, opening any page on the site tells us "this browser was here today", and nothing else.
• Usage analytics. We use Vercel Web Analytics, which is privacy-first: it does not use cookies and does not track or identify individual visitors. It only gives us aggregate figures like page views, referring sites, countries, and site performance.
• Site counters. We keep a handful of running totals: how many pages were viewed, how many separate visitors there were on a day, how many of those had been here before, which country they were in, and how many practice rounds were finished. Nothing in them identifies you. There is no account, no cookie and no tracking identifier of any kind.
• How returning visitors are counted. To know whether anyone comes back, your browser has to be recognizable as one we have seen before. Your IP address is combined with a secret value and turned into a one-way hash the moment your request arrives; only that hash is stored, and your address is never written down. The hash cannot be turned back into your address, we never try, and it deletes itself after 30 days without a visit. Your country comes from the network itself and is the only thing about your location that is recorded, never a city, never an address. This is an estimate by design: several people on one phone network share an address and may be counted as one visitor.
• Local storage. Your practice progress (which stages you've cleared, your streak, which lines you got wrong) is kept in your own browser, along with your sound and voice settings and which edition you read last. None of it is ever sent to us. The only things that leave your device are the anonymous "one more round was finished" tick described above, which says which language deck it was and nothing else, and, if and only if you turned reminders on, the "this browser was here today" ping described above.
• Technical data. We briefly process IP addresses to rate-limit our forms, to protect against abuse, and to produce the anonymous counts described above. They are never stored and never used to profile you.

How we use your information

• To send you product updates and respond to your messages.
• To send the practice reminders you asked for, and to stop sending them when you come back, when you ask us to, or after four.
• To understand overall traffic and improve the site.
• To see how much the site and the practice section are actually used.
• To protect the service from abuse.

Payments

There aren't any. Try Convi is free to use and we do not take payments or handle card details of any kind.

Sharing

We do not sell your personal information. We share data only with the service providers that make Try Convi work: our email provider (Resend) and hosting, data infrastructure and analytics (Vercel, Upstash), and only as needed to run the service.

Your rights

You can ask us to access or delete the personal data we hold about you at any time. Just email us and we'll take care of it. If you turned reminders on, the link at the bottom of any reminder deletes that record outright, immediately, without asking you anything.
