Through the Wall is an independent fan project run by Patrick MacQuarrie in Alberta, Canada. Privacy questions go to support@throughthewall.ca.
Through the Wall stores the information needed to run prediction pools: your sign-in identifier, email supplied by your authentication provider, username, pool memberships, predictions, progress, optional notification preferences, optional Heat Check ratings and flags, and feedback or support messages you choose to send.
Poolmates can see your username, public progress, and eligible scores. Predictions are hidden until the applicable lock conditions are met. Private-pool Heat Check scorecards are shared with that pool by default, and you can hide yours before saving. If you are registered for the season’s Global Pool, your saved Heat Check ratings still contribute to its anonymous combined averages. Global Heat Check shows combined averages and flag totals, not named individual scorecards. When a pool owner sends an email invitation, only that owner and the invitation recipient can see the invitation address. Invitations can be claimed only through the verified address supplied by the recipient’s sign-in provider.
Email notifications are off by default. If you opt in, Through the Wall may email you when new episodes become available or a friend completes a phase. Every email has an unsubscribe link, and you can also change notification choices in Settings. If someone stops invitations, Through the Wall keeps a hashed copy of the address so it is not emailed again. Queued email records are deleted automatically about a week after sending.
If you send a message through the feedback and support form, Through the Wall includes your account email and limited app context, such as the current screen, pool identifier, and season identifier, so the maintainer can understand and reply to the request. The message itself is excluded from analytics and masked from session replay. Support messages are sent to the project maintainer’s inbox.
Through the Wall uses Plausible Analytics for aggregate, cookieless traffic measurement and PostHog for product analytics used to understand invitation funnels, retention, feature use, and interest in possible paid features. After sign-in, PostHog associates product events with your Firebase user identifier. Through the Wall does not send your email address, username, prediction content, or Heat Check scorecards to PostHog.
PostHog uses cookies and browser storage and may record a replay of how you use the app. Form inputs are masked, elements that display account or invitation details are blocked from replay, and recorded URLs have their query strings removed before they are sent. PostHog data for this beta is hosted in its European Union Cloud region. Plausible continues to provide the separate aggregate traffic view.
You can turn product analytics and masked session replay off for this browser in Settings. The same control can turn them back on later.
Meta ads measurement is on by default for most visitors. It stays off until you allow it if you appear to be in the EU, EEA, UK, Switzerland, or Quebec, or if your browser sends a Global Privacy Control signal. In other regions, a notice offers a Turn off link. Your choice applies to this browser.
When measurement is on, the Meta Pixel sends page views, completed registrations, pool creation, and pool joins to Meta to measure and improve our Facebook and Instagram ads. Meta may use browser information and cookies for this purpose. We do not send your email address, username, predictions, ratings, or invitation links as event details. Pages whose links contain account or invitation details are excluded.
You can use Turn off in the notice or change Meta ads measurement in Settings at any time. Turning off usage analytics also stops Meta ads measurement. Turning it off stops future events from this browser; it does not erase events already received by Meta.
Firebase provides authentication, database, and server functions, Firebase Hosting hosts the website, and Resend delivers queued email. Plausible provides aggregate traffic analytics. PostHog provides identified product analytics, feature flags, and masked session replay. Meta provides advertising measurement. These providers process technical information needed to operate, improve, and secure the service.
Cloud Firestore data is stored in the nam5 United States multi-region. Cloud Functions run in us-central1 in the United States. PostHog data for this beta is hosted in its European Union Cloud region. Plausible processes and stores visitor analytics in the European Union. Resend delivers email for Through the Wall from its us-east-1 region in North Virginia, United States. When ads measurement is on, Meta processes those events in the United States.
Your data may be processed outside Canada, including in the United States and the European Union.
You can leave pools from Settings. You can also delete your account from Settings; this removes your profile, notification preference, invitations, invitation and feedback rate-limit records, game data, client error reports, and queued email associated with your account, and it deletes pools you own. Through the Wall stops sending analytics from the moment your account is deleted. Messages already delivered to an inbox, including support messages, cannot be recalled. Analytics records created before deletion and limited security and operational records held by service providers may be retained where reasonably necessary.
