Privacy Policy

Last updated: 27 August 2026

Walk Window ("we", "the app") helps you find the best time to step outside. This policy explains what we collect, why, and your choices. We do not sell your data. We do use measurement and advertising tools from Meta, Google and TikTok to understand how people find and use Walk Window — see Analytics & advertising for exactly what that involves and how to turn it off.

What we collect

• Location (precise or approximate) — used only to fetch local weather and compute your walk window. Your coordinates and a derived city name are stored on your account to power notifications and the morning forecast.
• An anonymous account identifier — created automatically (no name, email, or password required) so your streak and settings persist across launches.
• A push notification token — if you enable notifications, a device push token is stored so we can deliver reminders via Apple Push Notification service (APNs). It is used only to send you these notifications and is not shared with third parties.
• Subscription / purchase status — whether you have an active Window+ subscription.
• Mood check-ins — if you choose to log how you feel after a walk (a single tap: great, okay, or tired), stored on your account to show you your own wellness patterns over time. This is optional and you can skip it.
• Friends & social activity — if you invite a friend or accept an invite, we store the connection between your accounts and a feed of habit activity (such as windows caught, milestones reached, reactions, and nudges) so you can see and encourage each other. An optional display name you set is shown to people you are connected with.
• Basic usage — app sessions and notification interactions, to keep the app working.

How we use it

To generate your daily walk window, send the reminders you opt into, maintain your streak, and operate the Window+ subscription. We also measure how well our advertising works, as described in Analytics & advertising. We never use your location, your walk history, your streak or your mood entries for advertising — those stay inside the product.

Service providers

We share the minimum necessary with providers that process data on our behalf, each under their own privacy terms: Supabase (database & anonymous auth), Apple (Apple Push Notification service for reminders, and App Store In-App Purchases on iOS), Stripe (card payments on the web), Resend (transactional email), and Open-Meteo (weather; receives only coordinates), Google (Google Analytics 4), Meta (Meta Pixel and Conversions API) and TikTok (TikTok Pixel and Events API) — see Analytics & advertising.

Analytics & advertising

On the website (walkwindow.app) we use three measurement tools:

• Google Analytics 4 — how many people visit, which pages they read, and where they drop off. Used to improve the site.
• Meta Pixel and Conversions API — to see which of our ads actually lead to someone starting a trial, so we do not waste money on ads that do not work. Some of this is sent from our own server rather than your browser, because browsers increasingly block the browser version. In both cases Meta receives the event (for example "started a trial"), the page it happened on, an advertising identifier from a Meta cookie if you have one, and — for a purchase — an irreversibly hashed form of your email. We never send Meta your email in readable form.
• TikTok Pixel and Events API — the same purpose as the Meta tools above, for ads we run on TikTok. TikTok receives the event, the page it happened on, an advertising identifier if you have one, and — for a purchase — an irreversibly hashed form of your email. We never send TikTok your email in readable form.

What is never shared for advertising: your location, your coordinates, your city, your walk history, your streak, your mood entries, or anything you write. Those are product data and stay in the product.

Turning it off. Advertising cookies are off until you allow them. You can withdraw permission at any time by clearing this site's data in your browser, or by using your browser's "Do Not Track"/tracking-prevention setting, or an ad blocker — all of which we respect rather than work around. Turning it off does not change how Walk Window works.

The iPhone app (from version 1.0.3). The app now includes the same three measurement tools (Google, Meta and TikTok), and one extra safeguard that only exists on iPhone:

• You are asked first. After you finish setting up, iOS shows Apple's own permission box: "Allow Walk Window to track you across apps and websites?" If you choose Ask App Not to Track — or you never answer — no advertising identifier is used, and Meta, Google and TikTok receive nothing that could link you to activity in other companies' apps. The app works exactly the same either way.
• What is measured regardless of your answer is anonymous product usage: that a screen was opened, that a walk was logged, that a trial started. This is how we know which parts of the app people actually use.
• Still never used for advertising: your location, your coordinates, your city, your walk history, your streak, your mood entries, or anything you write.
• You can change your answer at any time in iOS Settings → Privacy & Security → Tracking.

Starting a subscription in the app reports that a free trial began — not a payment, because no money has been taken during the 3-day trial.

Retention & deletion

We keep your data while your account exists. You can delete your account and all associated data at any time from Settings → Delete Account in the app. Deletion is permanent. Note: deleting your account does not cancel an Apple subscription — manage that in your Apple Account subscriptions.

Your choices

You can disable location and notifications in iOS Settings at any time; core features that need location will be limited without it.

Children

Walk Window is not directed to children under 13 and does not knowingly collect their data.
