StudyAssistant is a completely free planner for school, college, and university. There is no subscription, no account, and no cloud copy of your diary. Your schedule, homework, TODOs, organizations, and profile stay on the device.
Free forever. Every feature is included. We do not collect personal identity — no email, no sign-in, no friends graph.
Classes, homework, TODOs, organizations, employees, subjects, settings, and your local profile work without the internet. The network is used only when you choose to share or import something, talk to the assistant, or import a timetable from a photo.
Keep school, college, courses, and university in separate organizations. Subjects, teachers, classrooms, and assignments stay grouped where they belong.
Photograph a timetable (table, diary, or weekly grid). Review the draft, fix times if needed, then apply it locally — including rooms and locations when they are on the image.
Build a repeating week and override a single day when the plan changes. Adjust start times, lesson length, and breaks without rebuilding the whole timetable.
Add homework and attach it to the next lesson of a subject. During the day the app already knows what is coming up, so you are not hunting through the week by hand.
Chat in the app about your local data. The assistant can look up organizations, subjects, and classes, then propose homework or TODOs — nothing is written until you confirm. History stays on the device. A shared daily quota keeps the service free for everyone.
Hand someone a short code or QR link for a schedule or homework item. They preview it, then import into their own local database. No friend list, no cloud profile, no permanent link.
Set the day’s goals and track them with a timer or stopwatch so focus sessions stay honest.
Keep personal tasks next to homework — with reminders, not with another login.
See the week’s load on the home screen and how many tasks sit on each day before it piles up.
Get alerts for the start and end of classes, unfinished homework, and a heavy day. Full reminder coverage is on Android; iOS is still catching up.

Your timetable, homework, messages, and profile do not leave the phone as a backup or an account. There is no sign-in and we do not collect personal data such as email, phone number, or a public user profile.
The only things that go over the network are what you explicitly send:
- a temporary share you create (encrypted in transit, short-lived on the server)
- an AI chat turn or a photo used to extract a timetable
- optional ads / a rewarded ad if you want extra AI messages
AppMetrica records crashes and coarse product usage so we can keep AI and sharing online without charging you. It is not a dump of your classes or homework, we do not sell study data, and we do not turn it into a marketing profile of you.
Short Yandex ads (and an optional rewarded ad for extra AI messages) exist for the same reason: they pay for the shared backend, not for unlocking the app.
