Privacy Policy

Last updated: September 14, 2026

SciEspresso is designed around data minimization. We collect only what is needed to provide app functionality and improve relevance.

1. Personal Information

We do not require account registration with name, address, or profile details to use the app.

2. Functional Data

We may process non-directly identifying app usage data such as device identifier, topic preferences, and interactions (for example likes/dislikes) to improve recommendations and app quality.

We also collect: the channel through which you discovered the app (e.g. Instagram, App Store search, or referral), onboarding interaction events (steps viewed, completed, or skipped with duration), and notification permission outcomes. This data is used solely to improve the product experience and is not shared with third parties for advertising purposes.

3. On-Device Processing

Standing Search descriptions entered by the user are processed entirely on-device. Raw text never leaves your device, only an anonymized semantic vector representation is synced to our servers to enable personalized paper matching. Your research interests are not stored or processed on our servers in readable form.

4. Payments

Subscriptions and payments are handled by the platform providers (Apple App Store and/or Google Play, depending on your device and region). SciEspresso does not store your full payment card data.

5. Data Deletion

You can stop data processing by uninstalling the app. For deletion requests and data inquiries, contact us using the email below.

6. Contact
