Privacy Policy

Stampede · Last updated 23 July 2026

Stampede (“Stampede,” “we,” “us”) is a mobile sports-reaction app where fans swipe to react to sports news and see how other fans voted. This policy explains what we collect, why, and the choices you have. By using Stampede you agree to this policy.

Information we collect

• Account information. When you sign up we collect your email address (used for authentication and account recovery) through our authentication provider.
• Profile information. A username, your selected favorite league and team, and an optional profile photo you choose to upload.
• Activity in the app. The votes you cast on cards, comments you post (including any GIF you attach to a comment), and the friends/accounts you follow. Votes and comments are associated with your account.
• Device information. Basic technical data needed to run the app, such as your device type and, if you opt in, a push-notification token.
• Usage analytics. Which screens you open and which features you use, so we can see what is working and fix what is not. We use PostHog for this. We do not use analytics for advertising and we do not track you across other companies’ apps or websites.

We do not collect precise location, contacts, or payment information, and Stampede is free to use.

How we use your information

• To create and secure your account and sign you in.
• To show your votes, comments, profile, and activity to you and, where applicable, to friends and other fans (vote tallies are shown in aggregate; your individual votes are visible to friends you connect with).
• To operate core features such as the swipe feed, results screens, comments, and the friend/follow system.
• To send notifications you have enabled.
• To keep the app safe: reviewing posted content against our community rules, and acting on reports.

How content is generated

Cards in Stampede are generated from publicly available sports news (ESPN RSS feeds) and processed by an AI service to write the card text. This content-generation process does not use or transmit your personal information.

How comments are moderated

Every comment is checked automatically when it is posted, and again if another fan reports it. To do this we send the comment itself to our AI moderation provider (Anthropic): the text you wrote, and, if you attached a GIF, a single still frame of that GIF. We do not send your name, email, or account identifier with it. The result is used only to decide whether the comment stays up, and moderation is fully automated. If a comment is removed you can reach us at the address below.

GIFs in comments

You can attach one GIF to a comment, chosen from a third-party catalog provided by Klipy. You cannot upload your own images or video, and GIFs cannot come from any other source.

• When you search for a GIF, the words you type are sent from our servers to Klipy, not from your device. Klipy does not receive your account, your email, or your device’s IP address with that search, and we do not store your searches.
• The GIF image itself is loaded directly from Klipy’s content network so we do not have to re-host it. That means your device requests the file from them, and, as with loading any image on the internet, they can see standard technical information such as your IP address and device type.
• Klipy has its own privacy practices, described at klipy.com.

How information is stored and shared

Your data is stored on our backend infrastructure provider (Supabase, which hosts our database and authentication). We do not sell your personal information. We share data only with the service providers needed to run the app and where required by law. Those providers are: Supabase (database and authentication), Expo (push-notification delivery), PostHog (usage analytics), Anthropic (AI card writing and comment moderation), Klipy (the comment GIF catalog), and Cloudflare (our website and shared-card links).

Data retention and deletion

We keep your information for as long as your account is active. You can permanently delete your account at any time from inside the app, in Settings → Delete Account. Deleting your account removes your profile, votes, comments, and follows. If you have uninstalled the app, you can also request deletion without reinstalling it at stampede.fans/delete-account, or write to us at the address below if you would rather we handle it or if you want a copy of your data.

Children

Stampede is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us information, contact us and we will delete it.

Your choices

• Edit your profile or favorite team at any time in the app.
• Turn push notifications on or off in the app or your device settings, by category or entirely.
• Report a comment or block a fan from the “…” menu on any comment; manage blocked fans in Settings.
• Delete your account in Settings (or via stampede.fans/delete-account), or request access to your data via the contact below.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected by the “Last updated” date above.
