When you send a screenshot, add a photo of yourself, or we write your words, that image or text goes to our server and on to Google’s Gemini AI, which reads it for us. Your three lines are written from the text it read, her chat or her profile, and its one-line notes on her photos, with anything you type under a result: by OpenAI’s GPT if you agreed to this policy in Gatzby 1.2.1 or later, otherwise by Gemini. OpenAI gets that text through Vercel’s AI Gateway and never gets an image. A photo goes with one-line notes on the other photos in your six; your words are written from those notes and, when you ask for one line again, from your current lines. When you ask What’s my move?, the result’s screenshots go to Gemini once more, and the text it reads from them, her chat or her profile and its notes on her photos, goes with the result’s three lines to Anthropic’s Claude AI, which writes the read on her; Claude never gets an image. Each request also carries a random id made on this phone, so we can count free uses. No name, no account, no contacts, no location.

Google processes it under its paid Gemini API terms, OpenAI under its API terms and Anthropic under its commercial terms, and none of them trains on it. Google keeps it only for a limited time to detect abuse; OpenAI keeps it up to 30 days to detect abuse, longer only where the law requires; Anthropic deletes it within 30 days, or keeps it up to two years if its safety systems flag it as breaking its usage policy. Vercel’s AI Gateway passes text on to OpenAI and keeps none of it. Our server runs on Expo’s EAS Hosting, on Cloudflare. The free-use counts live in Upstash, a database in Frankfurt.

Your past results: the read, the three lines and why, which one you copied, her name and her last message or profile line as the screenshot showed them, the read on her when you asked What’s my move?, and a small copy of each screenshot, up to three per result. Your six: a copy of each photo, its score, reading and fix, and the words written for it. The random id, and when you agreed to this policy.

No screenshots, photos or text. Each is read in memory and dropped once the answer is sent; it is never written to disk or to a log. To hold the free limits, it counts requests per random id and per IP address for up to eight days, and how many free chats a random id has used for up to a year.

We use PostHog, in the United States, to see how Gatzby performs: the random id, which events happened (a result shown, a line copied or all three turned down, a card shared, What’s my move? asked, the paywall shown, a purchase, a request or screen that failed), counts and timings, which AI model answered and how many tokens it used, and the plan and price of a purchase. Never the text of a chat or profile, never an image, and not your IP address.

Pro is bought through the App Store; Apple bills and refunds, and we never see your card. RevenueCat, in the United States, receives the random id and your purchase record, tells our server whether you’re Pro, and passes purchase events to PostHog.

A screenshot can show someone else’s name, messages or photos. We use it only to write your answer, and our server keeps none of it.

Settings > Delete my data removes your past results, the screenshot copies, any screenshot shared into Gatzby, and your six with its photos and words from this phone, at once. Deleting the app also removes the random id. Our server keeps nothing to delete. To have the analytics and purchase records tied to this phone removed, write from Settings > Support; the mail carries the id.

We read a screenshot or photo because you ask us to and agreed on first launch; we run analytics on our legitimate interest in keeping Gatzby working. Google, OpenAI, Anthropic, Vercel, PostHog, RevenueCat, Cloudflare and Upstash may process data in the United States under Standard Contractual Clauses. You can ask for access, correction, deletion or a copy, object to analytics, and complain to your data protection authority. Deleting the app withdraws your consent.

Gatzby is for adults. It is not meant for anyone under 18.
