Privacy Policy

Last updated: October 30, 2026

This policy describes how Interlib Dev LLC ("we", "us") handles personal data on this website and in our apps. Each app may have its own, more detailed policy, linked below.

1. This website

interlib.dev is a static website. It has no accounts, forms, advertising, or analytics, and it doesn't set cookies. Our hosting and network provider (Cloudflare) processes technical data such as IP addresses in server logs to deliver the site and protect it from abuse. Fonts are loaded from Google Fonts, so your browser connects to Google's servers, which receive your IP address (see Google's Privacy Policy).

When you email us, we receive your email address and the content of your message, and use them only to reply and keep a record of the conversation.

2. Our apps

Nooktune

A browser extension with an account (email, name and avatar from Google sign-in, plus your favorites, playlists and listening history). Full details: Nooktune Privacy Policy.

Savio

An expense tracker that works offline and doesn't require an account. Your expenses and settings are stored on your device; we don't receive them and don't operate a server for them.

3. Payments

Payments are processed by app stores (Google, Apple) or by our payment provider. We don't receive or store full card numbers. We receive what's needed to manage your purchase: email, country, what you bought and its status.

4. How we use data

• to provide and support our apps and services;
• to process purchases, refunds and requests;
• to keep our services secure and prevent abuse;
• to comply with legal obligations (for example, tax and accounting records).

We don't sell personal data, and we don't use it for advertising.

5. Sharing

We share data only with service providers that help us run our services (hosting, email delivery, payment processing), under their own privacy and security obligations, or when required by law.

6. Retention

We keep data while your account or our business relationship exists, and as long as the law requires afterwards (for example, payment records). You can ask us to delete your data at any time.

7. Your rights

Depending on where you live (for example, under GDPR or CCPA), you can ask to access, correct, export or delete your personal data, or object to its processing. Email support@interlib.dev and we'll respond within 30 days.

8. Children

Our services aren't directed to children under 13, and we don't knowingly collect their data.

9. Changes

We may update this policy. The date at the top shows the latest version; we'll notify users of material changes in the affected app.
