This page explains what data Drishti and Polyglyph Analytica have, and where it goes.

Last updated 3 October 2026.

Who is responsible

Polyglyph Analytica Ltd is the controller of the personal data this page describes. Its details are at the bottom of this page.

This website

This site uses analytics cookies only if you say yes. If you press "Allow analytics" on the cookie notice, Google Analytics records which of our pages you visit. It also records when you look at the prices.

This is recorded without your name or email. We use it to learn which pages help. Nothing is used for advertising. If you don't say yes, no analytics runs at all.

Apart from analytics, the site keeps two things in your own browser. One is whether you chose light or dark. The other is your answer to the cookie notice. Neither is sent anywhere. To answer again, use "Cookie settings" at the bottom of every page.

When Drishti is on sale

Drishti isn't on sale yet. When it is, it will run on your computer. Your figures and the reports it prepares stay there. None of it is uploaded to us. Its agents read what their job needs in your own Claude session, under your Claude account and Anthropic's terms. That never passes through us.

Your copy will send a licence check-in to our licence server. It carries a licence ID and an installation ID. The server uses them to tell whether your copy is licensed. Nothing from your figures is in it.

What we hold

When you buy, Paddle (our merchant of record) takes the payment and tells us your name, email address, country and the order. We keep that to deliver and look after your licence.

We send marketing email only if you said yes to it, anywhere, for any of our products. Saying yes means you agree to hear from Polyglyph Analytica about any of its products and apps, not only Drishti. It's one preference across all of them. Every marketing email has a one-click way to say no. Using it, or writing to us, stops marketing email from all of them. Update notices are part of the licence and aren't marketing.

Polyglyph Analytica keeps one customer list across all its apps. Paddle, our payment provider and merchant of record, holds it. Paddle also holds the record of what each person chose about marketing.

How long we keep it

We keep licence and purchase records for as long as the licence exists, and then for as long as tax law requires. We keep your marketing consent until you withdraw it.

Your rights

Write to hello@polyglyphanalytica.com if you want to:

• ask for a copy of what we hold about you;
• have it corrected or deleted;
• object to its use;
• withdraw a consent.

If you're unhappy with how we handle it, you can complain to the Information Commissioner's Office (ico.org.uk) or your own data protection authority.

Changes

If this policy changes, the date at the top changes with it.
