Privacy Policy

Korva is built so that your documents never leave your computer. There is no server to send them to. This page explains exactly what that means.

1. Who this applies to

This policy covers the Korva desktop app (including its free Reader & Converter tier) and this website (korva.korsund.com). “We”, “us” and “Korva” refer to the maker of Korva.

2. The Korva desktop app

The app does its work entirely on your own machine. Concretely:

• No telemetry. The importer, editor and PDF export never contact a server, and your documents never leave your machine. Korva makes only three kinds of outbound request, none containing your files and all described below: activating or deactivating a Korva Pro licence key with Polar, a licence check when Pro starts and the computer is online, and a check for app updates. These send the licence key, never your documents. There is no analytics and no usage tracking.
• No accounts. You don’t sign in. There is no user profile and nothing to log in to.
• No cloud, no sync. Your .pub, .kva and exported PDF files are read from and written to your local disk only.
• App updates. On launch Korva checks a public release feed for a newer signed version and can download and install it. These requests send no personal data and never upload your documents.
• Online activation and licence checks. When you enter your licence key, Korva sends a request to Polar’s licensing API containing only the key and a device label — never your documents. After that the app runs locally and re-checks the key when Pro starts and the computer is online; deactivating sends one more request. See the Terms of Service for the licence itself.

Because there is no server, we have no technical ability to see, collect, or recover your documents.

3. The free desktop tier

The free tier is the same Korva desktop app running in its free mode. It opens and edits any .pub file. A new user can export one complete project repeatedly; existing users keep the Free PDF access they had before this policy changed. The app stores only a local project marker to apply that allowance, and the export still happens entirely on your own computer. When you use it:

• Your file is processed locally on your device. It is never uploaded to us or anyone else.
• A short list of your recent files may be stored on your own computer so you can reopen them quickly. It stays on your device, is capped in size, and you can clear it at any time. We cannot read it.
• The first-project allowance and any restored previous-user access are stored in your browser-style local app storage on that computer. They are not sent to us.

4. This website

This marketing site collects as little as it can:

• Google Analytics. We use Google Analytics 4 to see which pages people visit, how they arrive and what they click. It sets first-party cookies (such as _ga) that tell repeat visits apart, and Google processes your IP address, device and browser details under Google’s privacy policy. We use it only for site statistics: Google signals and ad personalisation are switched off, and there is no remarketing and no ad pixel. Visitors in the EEA, the UK and Switzerland are asked first, and no analytics cookie is set unless they accept; you can change your choice any time in cookie settings. You can also block it with your browser’s cookie settings or the Google Analytics opt-out add-on; the site works the same without it.
• Cookieless counts. We also count page views with Cloudflare Web Analytics, which sets no cookie and reads no browser storage, and we count funnel events — downloads, checkout clicks and returns, conversion outcomes, and whether the pricing section was seen — only as anonymous daily totals. A stored total groups the date, event, coarse label, page, referrer host, campaign fields and country. There is no per-visit event row, visitor identifier, IP address, user-agent, file name or anything from a document you convert. A checkout return is not treated as proof of purchase; Polar’s order data remains authoritative. Clicking Buy still just links you to Polar’s secure checkout page on their own domain.
• Self-hosted fonts. Fonts are served from this domain, so no request is made to a third-party font provider.
• Hosting logs. The site is hosted on Cloudflare Workers. Like any web host, Cloudflare may process standard request data (such as IP address and user-agent) transiently to serve the page and protect against abuse, under Cloudflare’s privacy policy. We do not receive or store this data ourselves.

5. Buying Korva

Checkout is handled by Polar (polar.sh), our Merchant of Record, acting as the seller of record. When you purchase a licence:

• Your payment details (card number, billing address) are entered with and held by that provider. We never see or store your card information.
• We receive only what is needed to issue and support your licence — typically your name and email address, and your order reference.
• Your licence key is generated and emailed to you by Polar (and shown on your Polar order page and customer portal). You activate it in the app over a single online request to Polar. Your key never passes through us — to move to a new computer you deactivate in the app, or sign in to Polar’s customer portal yourself.

Please review your payment provider’s own privacy policy for how they handle checkout data and tax information.

6. Email you send us

If you email us for support, we’ll see your message and email address and keep it only as long as needed to help you. We don’t use it for marketing without your consent.

7. Children

Korva is a tool for general audiences and is not directed at children under 13. We do not knowingly collect personal data from children.

8. Your rights

Depending on where you live (for example under the GDPR or CCPA), you may have the right to access, correct, or delete the personal data a business holds about you. Because we hold so little — essentially the name and email attached to a purchase — such requests are simple. Email support@korsund.com and we’ll help.

9. Changes to this policy

If we change how Korva handles data, we’ll update this page and the “last updated” date above. Material changes will be reflected here before they take effect.
