Privacy policy
Last updated October 15, 2026
Seamday is a planner for students who also work. This page explains what we collect, why, who helps us run the service, and how to delete everything. Short version: we only keep what the planner needs, we don't sell data, and we don't show ads.
What we collect
- Account: your name, email address and a scrambled (hashed) version of your password. We never see or store the password itself.
- Profile: your time zone, country, whether you study, work or both, your school and graduation date if you add them, and which features you turned on.
- Your planner: terms, courses, classes, exams and homework, grades, workplaces, shifts, time off, events, tasks, reminders and the settings you choose.
- Notifications: if you allow browser notifications, the address your browser gives us for delivering them.
- Sign-in records: session details (such as the time, your IP address and browser type) to keep you signed in and protect your account.
Syllabus import
When you import a syllabus, the photo, file or text you choose is sent to Anthropic, whose AI model (Claude) reads it and returns the exams and homework it finds. Seamday does not store the file. Only the items you review and add are saved. Anthropic processes the content to provide this service under its commercial terms, which do not allow it to train its models on it.
How we use it
- To show your schedule, spot clashes and count down to deadlines.
- To send the reminders you set up, by notification or email.
- To send account emails, such as password resets.
- To keep the service secure and working.
We don't sell your data, share it for advertising, or use third-party analytics or tracking.
Who helps us run Seamday
These providers process data only to run their part of the service:
- Our hosting and database providers, which store and serve the app and your data.
- Resend, which delivers our emails.
- Anthropic, for syllabus import only (see above).
- Inngest, which tells our server when to check for due reminders.
- Your browser's notification service (for example Google, Mozilla or Apple), which delivers notifications to your device.
- Nager.Date, from which we load public holidays by country (no personal data sent).
Cookies
We use a sign-in cookie to keep you signed in and a cookie that remembers your light or dark theme. No advertising or tracking cookies.
Keeping and deleting your data
We keep your data while you have an account. You can delete your account at any time in Settings → Account → Delete account. This permanently removes your account and everything in it straight away. Copies in our providers' backups are removed when those backups expire.
Your rights
You can see and change your information in the app, and delete it all as described above. For anything else, including a copy of your data, email hello@seamday.com. Depending on where you live, you may also have the right to complain to a data protection authority.
Age
Seamday is for people aged 13 and over. If you are younger, please don't sign up.
Changes
If we change this policy, we'll update the date above. For important changes, we'll tell you in the app or by email first.
