1. Overview

Welcome to ReviewNotes ("the Service").

By using ReviewNotes, you agree to these Terms of Service.

If you do not agree, please stop using the Service.

2. Purpose

ReviewNotes helps users:

Register study problems (text or images)
Build personalized problem sets
Practice repeatedly
Track learning progress

The Service is designed for personal, non-commercial educational use.

3. Accounts and Access

Access is provided through Google Login (OAuth) only.
You are responsible for managing your own Google account.
ReviewNotes does not store or handle any Google passwords.

4. User Content

You own all content you upload, including notes, problems, and images.
ReviewNotes only stores and displays your content within your personal account.
Your data will never be shared, analyzed, or used for advertising.

5. Data Storage

All user data is securely stored on AWS Cloud Infrastructure.
We make reasonable efforts to maintain availability, but continuous access cannot be guaranteed.
Service operations may be modified or paused for updates or maintenance.

6. Payments and AI Credits

Each account starts with one note, up to 100 of your own problems, and 100 sign-up credits. Buying any credit pack lets you add more notes and problems while your credit balance is above zero. If it reaches zero, additions beyond the free allowance pause until you top up.
Notes and problems you have already saved are never locked. You can keep studying, building problem sets, using study schedules, printing, and running classes with saved content.
AI credits are consumed only when the Service performs AI work on your behalf — for example slicing questions out of a scanned page, extracting problems from a document, generating solutions, organising tags, or creating similar problems. The credits a feature uses are shown in the app where you use it, and may change.
Every account receives 100 AI credits on sign-up, once.
Additional credits are sold as one-time credit packs through our payment provider, Lemon Squeezy. Each purchase is a single charge. Purchased credits do not expire and are tied to your account.
Credits are consumed as the AI work is performed. Where an AI request returns no usable result, the credits reserved for that request are returned to your balance automatically.
If a purchase is refunded — by you, by us, or through your payment provider — the credits from that purchase are removed from your balance, including any portion you have already spent. This can leave your balance below zero, in which case AI features and additions beyond the free allowance stay unavailable until you purchase enough credits to bring the balance back above zero. Saved notes and problems remain available.
Credits have no cash value, cannot be transferred between accounts, and cannot be exchanged for money except where required by law.
Credit pack prices and per-feature credit rates may change. The 2026-10-15 unit-parity change converted existing balances at the $9.99-pack ratio (1,100/230); otherwise changes apply prospectively unless we announce another conversion. We will give reasonable notice of material changes.

7. Prohibited Use

You agree not to:

Upload unlawful or infringing materials
Attempt to access or modify data belonging to others
Use automated bots, scrapers, or exploit the Service for commercial resale

8. Limitation of Liability

The Service is provided "as is."

We are not liable for indirect or consequential damages arising from your use or inability to use the Service.

9. Modifications

We may revise these Terms periodically. Changes will be posted on this page with an updated effective date.
