About & policy
What this is
Bias Match compares two birth charts and returns one number. It is fan-made and unofficial. It is not affiliated with, endorsed by, or connected to any artist, group, label, or agency. It is entertainment, not advice, and it says nothing about anyone's real relationships, health, or character.
Where the data comes from
- Birth dates and birthplaces come from Wikidata, released under CC0.
- Birth times are used only when the person or their agency has stated them publicly. Each one carries a reliability grade, and anything unverified is treated as unknown.
- When a birth time is unknown, the reading runs on three pillars and the result is labelled hour unknown · 3 pillars.
- No photos, logos, or official marks are used. Names appear as plain text only.
Data & removal
Group member lists are read from Wikidata too, so they can lag a real lineup change: a debut, a hiatus, a departure, or a name spelled a different way may take a while to show up here. Nothing on this page is an official roster.
If you see a member who should not be listed, one who is missing, or a wrong birth date or birth time, write to ochg@hi-fit.kr with the group and what is wrong. Corrections and removals are handled within 24 hours, and we do not ask for a reason.
Your privacy
Your birth date, time, and country are used to calculate your chart. On the match page they travel with the request and are dropped once the answer is sent back; nothing is written down. Payments are handled entirely by Lemon Squeezy, our merchant of record, which also collects any tax and handles refunds; your card details never reach our server and we never see or keep them.
We do not store your raw birth date or time. Your report keeps only the chart facts it was written from (pillars, elements, sun and moon signs). Only that text and its access token are saved, so you can open the link again.
While a payment is in progress, your birth details sit in a single short-lived file so the purchase survives a server restart. Lemon Squeezy only ever receives a random reference to that file, never the details themselves. They are held for up to 30 minutes, then deleted.
Your browser keeps your birth details in sessionStorage only to carry them to checkout in the same tab; closing the tab clears them. Nothing else is stored on your device.
Minors
Anyone under 19 is never framed romantically. Those matches are written as friend or mentor energy, and romance wording is removed from the result.
Removal requests
If you are an artist, or represent one, and want an entry removed, write to ochg@hi-fit.kr. We remove it within 24 hours and do not ask for a reason.
