Privacy Policy
Last updated: November 7, 2026
Antithesia is operated by GRAXION LLC ("GRAXION," "we," "us"). Antithesia is a daily
question game: you vote on one question, predict what percentage of people chose your
answer, and the real split is revealed to everyone at the same moment — 9:00 PM Eastern.
Questions: hello@antithesia.com
1. Playing without an account
You never need an email address to play. When you first play, we silently create an
anonymous account for your device — no sign-up screen, no password, no name. That
anonymous account is how we keep one person to one vote per round and how your points,
streaks, and history are kept. If you clear your browser data without saving
(Section 2), you lose access to that anonymous account and its history.
2. If you choose to save
After your first reveal, we may offer to save your streak and history. Saving is
optional and uses a sign-in link sent to your email address — there is no password.
If you save, we store your email address, your votes, predictions, points, streaks,
and history so they can follow you across devices. You can also opt in to one email
per round at the reveal. We send no other marketing email.
3. What we collect
- Your play: the answer you chose each round, the percentage you predicted,
your points and streaks — stored on our servers under your account (anonymous
or saved), not only on your device
- Anonymous account: a randomly created account identifier for your device,
used to hold your play and prevent duplicate votes
- If you save: your email address (Section 2)
- If you turn reminders on: a push subscription for one notification per round,
sent at the reveal, containing no result ("Your results are in"). Opt-in only;
turning it off stops it immediately.
- Technical information: basic service logs (timestamps, error data) needed to
run and secure the service
4. The promise — your votes are never sold
**We never sell your votes, your predictions, or your personal information. We do not
share them with data brokers or advertisers, and Antithesia runs no advertising and
no ad trackers.** Aggregate round results (for example, "62% chose Yes") are the
product itself — they are published as round results and never identify any person.
On leaderboards, players appear only under automatically assigned aliases — never
real names, and Antithesia offers no player-chosen display names.
5. Your Opposite
A later feature, Your Opposite, matches you with the person whose answers differ most
from yours. It is the one part of Antithesia that requires an email address — no
exceptions. Matching is based on answers, not identities. The full consent, safety,
and data rules for this feature will be published before it launches and do not apply
until then.
6. Who we share with
Only the services that make Antithesia run, and only what they need:
- Supabase — database and sign-in hosting
- Cloudflare — website and API hosting
We may also disclose information when the law requires it, or to protect someone's safety.
7. Deleting your data
If you play as a guest, clearing your browser data ends your access to your anonymous
account and its history. Play stored under an anonymous account that has been inactive
for 12 months is deleted. If you saved with an email, you can ask us to delete your
account and saved play at hello@antithesia.com; deletion removes your email, votes,
predictions, points, and history from our active systems. Backup copies may persist
briefly and are then overwritten.
8. Security
We use industry-standard encryption in transit, access controls, and per-product
isolated systems (Antithesia's data is stored separately from every other GRAXION
product). No system is perfect; if we learn of a breach affecting your information,
we will tell you as the law requires.
9. Children
Antithesia is for players 13 and older. We do not knowingly collect personal
information from children under 13. If we learn that an account belongs to a child
under 13, we will delete the account and its play.
10. Changes
If we change this policy in a meaningful way, we will update this page and note the
new date before the change takes effect.
