Privacy Policy

Last updated November 3, 2026

This policy covers the Cupola iPhone app and cupola.markets.

Information we collect

When you create an account, we collect your email address, username, and profile details. You can choose to add a phone number or profile photo. We also keep your predictions, orders, trades, balances, rewards, messages, friendships, and account settings.

We process device and app information, IP addresses, security logs, and notification tokens to operate and protect the service. The website uses Cloudflare traffic and performance analytics. If you join the website waitlist, we save your email and the approximate country, region, and city reported by Cloudflare. We do not request your precise location.

How we use it

We use this information to sign you in, run and settle predictions, maintain balances and rewards, show profiles and standings, support social features, send notifications you allow, answer support requests, and prevent abuse. We do not sell your personal information or use it for targeted advertising.

What other people see

Other members can see your profile, record, standings, and messages. Your invite link can show your name and profile photo outside the app. Your positions appear according to the app’s sharing features and your settings, including holdings shown beside your chat messages. Your email address, phone number, and account balances are not public.

Permissions and service providers

Contacts and notifications are optional. If you use Find friends, the app sends one-way codes made from contact information to find members who allow contact matching; the server does not keep those lookup codes. You can change device permissions in iOS Settings and your sharing preferences in Cupola.

We use Supabase for accounts and data, DigitalOcean for our servers, Cloudflare for the website and security, and Expo and Apple for notifications and app security. These providers process information to deliver their services and must protect it consistently with this policy. We may also disclose information when required by law or to protect people and the service.

Retention and account deletion

We keep information for as long as needed to provide Cupola and protect its records. You can request account deletion in the app’s Settings. The app shows when deletion will complete and lets you cancel during that period. When it completes, we remove your profile, contact details, photo, and message content, and delete your sign-in account.

Limited pseudonymous trade, balance, audit, and anti-abuse records remain so existing positions can settle, records stay accurate, and signup bonuses are not paid twice. Your old username remains retired.
