Privacy policy
Effective Nov 5, 2026 · There's no sign-up, and we keep almost nothing about people.
This is a translation of the Korean original. If the two differ, the Korean version applies.
What we keep
| What | Why | How long |
|---|---|---|
| Checkup results (address, score, phone screenshot, some page text) | To be quick when the same address is looked at again | 10 minutes (AI text: a day) |
| A transformed value (hash) of the site's address and its latest score | The score curve (top N%) | Deleted if the site isn't checked again for a year |
| Running statistics: daily counts of what happened (checkups, cache hits, times consent was turned off, phone browser successes and failures, AI calls and tokens, leaderboard listings and reports, share button taps and visits through share card links, answers to 'Does this score seem right?' by score range, and so on). No people or addresses | Running the service and checking costs | 2 years |
| For sites on the leaderboard: the address, score, title, type and strengths, the description, the tool it was built with, strong areas, the preview image address and a phone picture of the first screen (images are shown through our server, so people viewing the leaderboard don't connect to that site separately) | The leaderboard | Until the tag is removed or the site goes unchecked for 60 days |
| Reports (a value made from the IP address that changes every day) | So the same person can't report many times | Until that site is listed again or deleted |
| One-line feedback left on leaderboard sites (the text, when, which site) and a value that tells writers apart for a single day only (made irreversibly from the IP address and the date). The text is public | Showing it on the leaderboard and that site's results screen; limiting how many can be left a day | Until that site comes off the leaderboard (hidden posts are deleted with it) |
| Reactions (counts of each kind per site), a value used to count the same reaction only once a day (made irreversibly from the IP address, date and site), feedback reports (the post number and a transformed IP address) | Counting reactions; stopping duplicates and repeated reports | Counts and reports until the site comes down; the duplicate-check value, 2 days |
| One score a day for each leaderboard site | The 'Most improved this week' sites | 90 days |
| Checkup records: the score, the scores and small checks for each item, the tool it was built with, figures measured on the phone (download size, number of requests, full load time, number of errors, what sharing did), the kinds of cautions. Addresses grouped only by their transformed value (hash) | Making checkups better (below) | 2 years. Not kept if you turn off the consent under the address box |
| Specialist Care code, site, checkout session number, date, amount | To open Specialist Care and check whether it was refunded | 1 year after the code ends (tax records are kept separately by Link, the seller) |
| Refund requests (the code and when it was requested) | To make the refund | Along with the code |
| Weekly checkup records: the site address, code, the day it was turned on, each week's re-check, answers about visits (whether they went up, the visits-a-day range) | Showing the site's owner how things change, and learning which fixes really help | Deleted as soon as it's turned off. If left on, until Specialist Care ends (answers: 2 years) |
| In this device's browser: whether you turned off 'Use my checkup results' and your Specialist Care code (localStorage) | To remember your choice, and to open Specialist Care right away next time | Until you clear it in your browser |
| In this device's browser: for each site, the address, score and item scores from your last checkup, the reactions you tapped today, and when you answered about a score (localStorage, never sent to the server) | 'Sites checked on this device' on the front page, the 'score raised by fixes' card when a score goes up, showing the reactions you tapped | Until you clear it in your browser |
There's no sign-up, so we don't take names, email addresses or phone numbers. We don't use cookies.
Only when you email us do we receive the sender's email address and the message. 1 in 200 Million is run together with 1 in 8 Billion (1in8b.life) by the same operator, so the two share contact addresses (contact@1in8b.life, privacy@1in8b.life). Emails pass through Cloudflare's email forwarding and are kept in the operator's Gmail (Google). They are used only to reply and to handle questions, payments, refunds and privacy requests. The operator reads and sorts emails with the AI assistant Claude (Anthropic), which drafts replies, but the operator checks each reply and sends it personally, and decisions are never left to AI. Emails are deleted 3 years after they've been handled. Usage records of the two services are never passed between them or combined.
Who we send things to
| To whom | What | Why |
|---|---|---|
| Cloudflare, Inc. (USA and elsewhere) | Access logs, addresses to check, email questions | Running the site, the browser that opens the phone screen (Browser Rendering), forwarding email to the operator's inbox |
| Anthropic, PBC (USA) | Checkup results, some text from the page's first screen, the phone screenshot, the preview image address, email questions (when the operator drafts a reply) | The note and ideas fitted to each site, Specialist Care text (Claude API), sorting email and drafting replies. Not used to train models. |
| Stripe, Inc. and its affiliates (including Link; USA and elsewhere) | What you enter on the payment screen when you pay, and which site's Specialist Care it is | As the merchant of record: payment, tax, receipts and refunds. The operator can see payment records (including email) in the Stripe account. |
| Google LLC (USA and elsewhere) | What you write in Send feedback, email questions | Receiving feedback (Send feedback doesn't collect email addresses), receiving and answering email (Gmail) |
Learning from checkup results
We collect these, with your consent, to learn what really helps a site spread.
- Checkup records. When 'Use my checkup results to make checkups more accurate' under the address box is on (it starts on, one tap turns it off, and this browser remembers), we keep only the technical details of that result. We don't keep page text, screenshots, what AI wrote, or who ran the checkup. We keep only one per site per day.
- Weekly checkup records. Only when a site's owner turns on 'Weekly checkups' inside Specialist Care do we re-check that site once a week (the engine only, with no browser and no AI). After two weeks we ask once, 'How were visits after your fixes?' Turn it off and the re-check records and your answers are deleted right away.
We use what we collect to improve the scoring rules and the fixes. Outside, it is only published or written about as grouped statistics where no site can be recognized (for example, 'N% of sites that fixed their share button…'), and we never sell the records or pass them on. We don't hand them over to train AI models either. If a site's owner wants that site's records deleted, send us the address through Send feedback.
About the sites we check
The service reads only the public pages at the address you put in. If it finds something that looks like an email address or account number in the page code, it only counts them; it never shows or keeps what they say.

Questions and deletion
Tell us at privacy@1in8b.life or through Send feedback, and we'll check and delete it. On the leaderboard, removing the verification tag takes your site down right away.
