Security

Last updated: [DATE]

Your plans are personal, and we treat them that way. eudy is built on trusted, industry-standard infrastructure, and we keep the design deliberately simple — we collect little, and we never sell your data. This page explains the main measures that protect your information.

Encryption

All traffic between your device and eudy is encrypted in transit using HTTPS (TLS). Your account data and content are encrypted at rest within our cloud infrastructure provider's managed storage.

Trusted infrastructure

eudy runs on Google Cloud Platform via Firebase, including Firebase Authentication and the Cloud Firestore database. This means your data is hosted in Google's secure, professionally operated data centers, with the physical, network, and redundancy protections Google maintains for its cloud services.

Account access

You can sign in with Google (using Google's OAuth, so eudy never sees your Google password) or with an email address and password. Authentication is handled by Firebase Authentication. Access to your content is scoped to your account, and our database security rules are configured so that you can only read and write your own data.

Secure payments

Purchases are handled by established payment providers — Stripe on the web, and the Apple App Store or Google Play within the mobile apps. Card details are entered and processed by these providers, which maintain PCI-DSS compliance; eudy never receives or stores your full payment card number.

Data reliability

Your content is stored in Google's managed Cloud Firestore, which replicates data across infrastructure to guard against loss. Because the planner also stores a copy on your device, your current week remains available even when you are offline.

Your controls

You can review and edit your data at any time within the app, and you can permanently delete your account and its associated content from the Settings screen. See our Privacy Policy for details on what we collect and how it is used.

Reporting a vulnerability

We welcome reports from the security community. If you believe you have found a security vulnerability in eudy, please email security@eudy.app with the details and steps to reproduce. Please give us a reasonable opportunity to investigate and address the issue before any public disclosure, and avoid accessing or modifying other users' data. We appreciate responsible disclosure.
