Stridy Privacy Policy
Last updated: 13 July 2026
1. Who We Are
Stridy is an environmental cleanup app that helps people track and measure their impact when picking up litter. This Privacy Policy explains what data we collect, how we use it, and your rights over your data.
- Company: STRIDY LIMITED
- Address: 8 Cross Street, Manulife Tower, #20-01, Singapore 048424
- Contact: hello@stridy.com
- Website: stridy.com
- App: Stridy (available on iOS and Android)
- Online Shop: stridy.com/shop
- Impact Dashboard: stridy.com/community-impact-dashboard (also accessible at data.stridy.com)
Stridy is used by people around the world. This policy covers the Stridy mobile app, the Stridy website (stridy.com) including the online shop, and the Stridy Impact Dashboard, regardless of where you are located.
2. What Data We Collect
Account Information
When you create a Stridy account, we collect:
- Username: a display name you choose, shown in the app and on the public Impact Dashboard. We strongly recommend that you do not use your real name as your username. Choose a nickname or alias instead, as your username is publicly visible (see Section 4). Stridy is not responsible for any consequences if you choose to use your real name.
- Email address: used for account login and password resets
- Password: stored securely using encryption (we never store or see your actual password)
- Profile image: optional, displayed on your profile and in activity feeds
Social Login Data
If you sign up using Google, Facebook, or Apple:
- We receive your name and a unique account ID from the provider. Your name from the social login provider may be used as your initial username, which you can change in your profile settings.
- If you sign up via Facebook, we may fetch your profile photo
- We do not store your social media password or maintain ongoing access to your social accounts
GPS and Location Data
When you start a stride (cleanup walk), the app records:
- Precise GPS coordinates throughout your walk. This is detailed location tracking that records your position approximately every minute
- Start and end coordinates of each pickup event within your stride
- Your general location (country, state, city), determined automatically from your GPS coordinates
Location tracking only happens while you are actively doing a stride. The app does not track your location in the background or when you are not using it.
Activity Data
During and after strides, we collect:
- How long your stride lasted and the distance you walked
- The types and quantities of litter you collected
- The weight of litter collected
- Photos you take during your stride (optional)
- Any text descriptions you add
- Points earned
- Which team you were striding with (if any)
Device Data
- Push notification ID: so we can send you notifications about the app
- Device authentication token: to keep you logged in on your device
Newsletter Subscription
After signing up, you may choose to subscribe to the Stridy newsletter (“Stridy Seconds”). This is optional and separate from creating your account.
Stridy Website (stridy.com)
When you visit the Stridy website at stridy.com, we may collect:
- Analytics data: we use Google Tag Manager to understand how visitors use our website. This may include information such as pages visited, time spent on the site, referring website, and general location (country/city level). This data is collected anonymously and is not linked to your Stridy app account.
- Essential website data: standard web server logs and cookies necessary to operate the website (see Section 10).
The Stridy website is hosted by
Hostinger and is separate from the Stridy app infrastructure.
Online Shop (stridy.com/shop)
If you make a purchase through the Stridy online shop, we collect:
- Your name and shipping address: to deliver your order
- Email address: to send order confirmations and shipping updates
- Payment information: when you pay by credit or debit card (e.g., Visa, Mastercard), your card details are processed securely by Stripe, our payment provider. We do not see or store your full card number on our servers. Stripe handles this directly.
Impact Dashboard (data.stridy.com)
When you visit the public Stridy Impact Dashboard, we use
Microsoft Clarity to understand how the page is used. Clarity records how visitors interact with the dashboard, such as clicks, scrolling, and mouse movement (shown to us as heatmaps and session playbacks), together with technical information such as your IP address, device type, and browser. We do
not use this to identify you, and the dashboard has no login and no fields for you to enter personal details. This is separate from your Stridy app account.

data.stridy.com. Both display the same data and are publicly accessible; anyone can view them without logging in.
The following data is visible on the public dashboard:

- Stride locations: the GPS coordinates of where you did each cleanup, shown as points on the map
- Activity stats: number of items collected, distance walked, duration, and points earned per stride
- Leaderboard ranking: your username and performance stats compared to other users
This data is also accessible through our public API (application programming interface), which is how the dashboard website loads the data.
By using Stridy, you understand and agree that your username and stride activity data will be visible to the public on the Stridy Impact Dashboard.
