Privacy policy

Who we are

Purrank is run by Siddharth Sharma, an independent developer. For anything about your data, email sid@purrank.app.

What we collect

• Your email address, to sign you in with a one-time code, or from Google or Apple when you sign in with them. Apple may give us a private relay address instead.
• Your cats: their names, photos and captions. These are public: anyone can see them on the boards and on each cat’s page.
• Your rough location, only if you allow it. When you add a cat or use “My location”, the app rounds your position to about 1 km and sends it once. We look up the nearest town and keep only its city and country, which appear with your cat. We never store your coordinates.
• Purchases: the credit packs and treats you buy, and the treats you give. Payments go through Stripe on the website, and through the App Store or Google Play in the apps. We get a confirmation of what was bought, never your card details. Spotlight shows how many treats each cat has received.

We don’t show ads, we don’t sell your information, and we don’t track you across other apps or websites.

How we use it

To run Purrank: sign you in, show your cats, rank them, deliver what you buy, and send Cat Help its share. The AI Judge looks at each photo to check that it shows a cat and to split its points across the categories.

Who helps us run Purrank

These services process data for us, only to provide Purrank:

• Supabase (database and sign-in, United States)
• Cloudflare (photo storage and network)
• Vercel (website and API hosting)
• OpenRouter and the AI model it routes to (judging photos)
• Resend (sign-in emails)
• Stripe, Apple and Google (payments and sign-in)

Town names come from GeoNames data that we keep on our own server, so your location isn’t sent to them.

Deleting your account

In the app, open Profile and tap Delete account. This removes your account, your cats and their photos, and your unused credits, straight away. You can also email sid@purrank.app from your account’s address and we’ll delete it for you.

We keep the record of treats you gave, without your name, so Spotlight and Cat Help totals stay correct. Payment providers keep their own records as the law requires.

Reporting content

Every cat page has a Report button. We review reports and remove anything that breaks the rules: photos must show a cat and nothing offensive. You can also hide a cat’s owner so you no longer see their cats.

Children

Purrank isn’t meant for children under 13, and we don’t knowingly collect their information.

Changes

If this policy changes, we’ll update it here and change the date at the top.
