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.
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.
When you create a Stridy account, we collect:
If you sign up using Google, Facebook, or Apple:
When you start a stride (cleanup walk), the app records:
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.
During and after strides, we collect:
After signing up, you may choose to subscribe to the Stridy newsletter (“Stridy Seconds”). This is optional and separate from creating your account.
When you visit the Stridy website at stridy.com, we may collect:
The Stridy website is hosted by Hostinger and is separate from the Stridy app infrastructure.
If you make a purchase through the Stridy online shop, we collect:
| Data | What we use it for |
|---|---|
| Username and email | Create and manage your account, let you log in, send password resets |
| GPS coordinates | Track your cleanup route, calculate the distance you walked, show your stride on the dashboard map |
| Activity data (items, weight, time) | Calculate your environmental impact, award points, show your stats on the leaderboard |
| Photos | Display alongside your stride record in the app and on the dashboard |
| Push notification ID | Send you notifications about app updates, events, and activity |
| Newsletter subscription | Send you periodic emails about Stridy news and events |
| Website analytics | Understand how visitors use stridy.com so we can improve the website |
| Shop purchase data (name, address, email) | Process and deliver your order, send order confirmations and shipping updates |
We do not sell your data to anyone. We do not use your data for advertising.
Anonymised stride data may be shared with universities, researchers, or organisations for studies related to civic engagement, volunteering, community behaviour, or environmental impact.
When sharing data for research purposes:
This data is only shared in anonymised, aggregated form and is used strictly for research, education, or public interest purposes.
If you are located in the European Union or United Kingdom, data protection law (GDPR) requires us to have a legal basis for processing your personal data. The table below explains the legal basis we rely on for each type of processing:
| Data / Processing | Legal Basis | Explanation |
|---|---|---|
| Account data (username, email, password) | Contractual necessity | We need this to create and manage your account — without it, we cannot provide the service |
| GPS and location tracking during strides | Contractual necessity | Location tracking is a core feature of Stridy — it is how we track your cleanup route and calculate distance |
| Activity data (items, weight, photos, points) | Contractual necessity | Recording your cleanup activity is the primary purpose of the app |
| Push notifications | Consent | You can enable or disable notifications on your device at any time |
| Newsletter (Stridy Seconds) | Consent | You actively opt in during or after signup, and can unsubscribe at any time |
| Public display on Impact Dashboard | Legitimate interest | Showing collective cleanup impact is central to Stridy’s mission of encouraging environmental action. You are informed of this before using the service |
| Website analytics (Google Tag Manager) | Legitimate interest | We use anonymised analytics to understand how visitors use our website so we can improve it |
| Research and studies (anonymised data) | Legitimate interest | Anonymised data supports environmental research and public interest. Your username and email are never included |
| Error reporting (Sentry) | Legitimate interest | Detecting and fixing bugs keeps the app working properly for all users |
If we rely on legitimate interest, you have the right to object (see Section 8).
The Stridy Impact Dashboard shows cleanup activity on an interactive map. It is available at stridy.com/community-impact-dashboard (embedded within the Stridy website) and also at 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:
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.
We share some of your data with the following services to make Stridy work:
Your data is stored in the following locations:
This means some of your data is transferred outside of Singapore. We rely on the data protection practices of these service providers to keep your data safe. Where applicable, these transfers are conducted in compliance with the PDPA (Singapore) and GDPR (EU/UK).
You have the following rights over your data. Some rights apply to all users, while others are specific to users in the European Union or United Kingdom under the GDPR.
You can view your stride history, stats, and profile information in the app at any time.
You can edit your username and profile image in the app.
You can delete your account from the app (go to Profile > Edit Profile > Delete Account). This will permanently delete your account and all associated stride data, GPS records, and collected item records.
Contact us at hello@stridy.com and we will provide you with a copy of the personal data we hold about you.
If you are in the EU or UK, you can request your personal data in a structured, commonly used, machine-readable format so that you can transfer it to another service.
If you are in the EU or UK, you can ask us to temporarily stop using your data while we resolve a concern — for example, if you believe your data is inaccurate or you have objected to our processing.
If you are in the EU or UK, you have the right to object to processing based on legitimate interest (see Section 3). This includes the public display of your data on the Impact Dashboard and the use of anonymised data for research. If you object, we will stop processing your data for that purpose unless we have compelling legitimate grounds to continue.
To exercise any of these rights, contact us at hello@stridy.com.
You can unsubscribe at any time using the link in any Stridy email, or by contacting us.
If you believe we have mishandled your data:
Stridy is not intended for children under 13 years of age. If you are under 13, please only use Stridy with the permission and supervision of a parent or guardian.
We do use Stridy in school engagement programmes. In these cases, participation is supervised by teachers and school staff.
If we become aware that we have collected data from a child under 13 without appropriate consent, we will take steps to delete that data. If you believe a child under 13 has created an account without parental consent, please contact us at hello@stridy.com.
The Stridy mobile app does not use cookies. It uses secure authentication tokens to keep you logged in.

The dashboard uses Google Maps, which may set its own cookies. See Google’s privacy policy for details.
Some browsers send a “Do Not Track” signal when you visit websites. Our service does not currently respond to Do Not Track signals, as there is no industry standard for how to do so.
We may update this Privacy Policy from time to time. When we do, we will update the “Last updated” date at the top of this page. We encourage you to review this page periodically.
For significant changes that affect how we use your data, we will make reasonable efforts to notify you through the app or by email.
