Privacy Policy
Last updated October 28, 2026
Hashmark ("we") runs hashmarkoprops.com, a sports prop research app. This page says what we collect and why. We don't sell your information.
What we collect
- Your account: your email address, an optional name, and your password stored only as a salted scrypt hash (we can't read it).
- Subscriptions: payments are handled by Stripe. We never see or store your card number; Stripe tells us whether your subscription is active.
- Visits: a random ID in your browser, the pages you open, where you came from (for example "Instagram") and whether you signed up. We don't store IP addresses in this log, and it's deleted after 60 days.
- Security: to stop attacks, our firewall briefly keeps the network address of requests that break its rules (bans last minutes to a day).
- On your device: your Betslip, tracked bets, follows and settings are saved in your browser, not on our servers.
- Notifications: if you turn on alerts, your browser gives us a push address so we can send them. Turn alerts off and it's removed.
- Ads measurement: when enabled, the Meta Pixel tells Meta that a visit, sign-up or subscription happened, so we can measure our ads.
How we use it
To run your account and subscription, send the alerts and emails you ask for, run the Beat the Bots contest, keep the site secure, and understand which posts and pages bring people in.
Who else handles it
Stripe (payments), Render (hosting), Meta (ads measurement, if enabled) and our email provider, each only for that job.
Your choices
You can change your name and password or delete your account (and its data) any time under Account. Deleting your account removes it from our records; Stripe keeps payment records as the law requires. For anything else, send a message to @hashmarkprops on Instagram.
Age
Hashmark is for adults 21 and older. We don't knowingly collect information from anyone younger.
