Privacy Policy
Effective Date: October 2026 • Last Updated: Academic Year 2026–2027
1. Overview & Client-Side Privacy Commitment
At Class Schedule Maker & Gap Optimizer ("we", "our", or "us"), accessible via classscheduleoptimizer.com, we prioritize the absolute privacy and data sovereignty of students and educators. Our tool is architected on a zero-backend model: none of your course codes, class timings, notes, or schedules are ever transmitted to or stored on our servers.
2. Browser LocalStorage Data Transparency
To ensure that your work is not lost when you refresh the webpage, our tool utilizes your browser's native localStorage API under the key class_schedule_optimizer_state_v2. This data resides solely on your physical computing device. You may completely purge this data at any moment by clicking the "Reset" button within the scheduler toolbar or by clearing your browser cache.
3. Google AdSense & Third-Party Advertising Disclosures
We may display advertisements served by Google AdSense to fund server infrastructure, bandwidth, and ongoing algorithmic research.
- Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to our website or other websites across the Internet.
- Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visit to our sites and/or other sites on the Internet.
- Users may opt out of personalized advertising by visiting Google Ads Settings or by navigating to www.aboutads.info.
4. GDPR (General Data Protection Regulation) Rights
Under the European Union General Data Protection Regulation (GDPR), users are entitled to rights of access, rectification, erasure, and data portability. Because our software executes completely on the client side without storing personally identifiable information (PII) on external databases, you maintain complete autonomous control over your data directly within your web browser.
5. CCPA (California Consumer Privacy Act) Disclosures
We do not sell, rent, or trade your personal information. We do not collect student educational records governed under FERPA (Family Educational Rights and Privacy Act). All timetable generation operations occur strictly in local client memory.
