Privacy Policy

Last updated: 21 October 2026

ClassBuddy ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard information when you use the ClassBuddy mobile application and platform, and when you visit our marketing website at classbuddycy.com.

1. Information We Collect

We collect the following information when you use ClassBuddy:

Name — to identify you within your institution and personalise your experience.
Email address — for account authentication and communication.
Phone number — for parents/guardians, to keep the institution's records up to date.
User ID — a unique identifier used to link your account to your institution.
Device token — to send you push notifications about lessons, homework, grades and announcements.
Academic records — attendance, homework, grades and assessment comments entered by your institution.
Billing information — charges, invoices and payment status. Card details themselves are never collected or stored by ClassBuddy — see Section 3.

2. How We Use Your Information

We use the information we collect solely for the following purposes:

To provide and operate the ClassBuddy platform and mobile app.
To display your schedule, homework, grades, billing and announcements.
To send you push notifications relevant to your school activity.
To process payments on behalf of your institution.
To authenticate your account and ensure secure access.

We do not use your account or academic data for advertising or marketing purposes, and we do not sell it. Our public marketing website uses separate, consent-based cookies described in Section 4 — these never mix with your ClassBuddy account data.

3. Third-Party Service Providers

We do not sell or trade your personal data. To operate the service, we share the minimum necessary data with the following service providers, each acting under their own privacy and security obligations:

Stripe — processes online payments. Card and bank details are entered directly into Stripe and never pass through or get stored on ClassBuddy's servers. Stripe may also collect identity/KYC information directly from institutions during payment account setup.
Expo — delivers push notifications to the ClassBuddy mobile app. Notification content (e.g. a grade, a homework title, an overdue amount) and your device token are sent to Expo solely to deliver the notification.
SMS.to — delivers SMS to parents/guardians when an institution sends one (for example about homework feedback). The parent's phone number and the message text are sent to SMS.to solely to deliver the SMS. A parent who no longer wants SMS can ask the institution to switch them off.
Our hosting provider — stores the application database and infrastructure that ClassBuddy runs on.
Sentry — receives crash and error reports from the ClassBuddy mobile app so we can fix bugs. Reports are stored in the EU and contain device and app details and the user ID of the signed-in account, not grades or messages.

Within your institution, your data is only accessible to your institution's authorised staff and ClassBuddy platform administrators for support and maintenance purposes. If your institution requires a formal Data Processing Agreement covering these arrangements, see Section 10.

4. Cookies and Website Analytics

Our marketing website (the pages you're browsing before signing in) uses cookies for these purposes: remembering your language preference, and — only if you accept — the Meta (Facebook) Pixel, which helps us understand how visitors find our site so we can run more effective ads, and PostHog analytics, which records page views, clicks and anonymised session recordings (form fields are masked) so we can improve the site. Neither sets cookies until you accept them in the cookie banner. Before that, or if you reject, PostHog only counts page views and clicks anonymously, without cookies or local storage: visitors are told apart by a hash that changes daily and cannot identify you, and nothing is recorded. Neither is used inside the ClassBuddy app itself. You can change your choice at any time using the "Cookie preferences" link in the site footer.

5. Data Storage and Security

Your data is stored on secure servers, with access restricted to authorised personnel. We implement appropriate technical and organisational measures — including encrypted connections and hashed passwords — to protect your personal information against unauthorised access, loss, or misuse.

6. Data Retention

We retain your personal data for as long as your account is active or as required to provide the service to your institution. If you wish to have your data deleted, please contact your institution's administrator or contact us directly, and we will action the request within a reasonable timeframe.

7. Children's Privacy

ClassBuddy is used in educational institutions and is used by students who are minors, including children under 14 (the age of digital consent in Cyprus under Law 125(I)/2018). We do not collect any information beyond what is necessary for the educational service. All accounts are created and managed by the institution, not directly by minors. The institution processes students' data under its agreement with the parent or guardian, and is responsible for informing parents and for obtaining consent for anything that goes beyond running the classes, such as publishing photos of students.

8. Your Rights

You have the right to access, correct, or request deletion of your personal data. Please contact your institution's administrator or reach out to us at the email below.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated date.

10. Data Processing Agreement

If your institution requires a formal Data Processing Agreement covering how ClassBuddy processes personal data on your behalf, you can review and request one on our Data Processing Agreement page.
