How can we help?

Open the project and use Share. You can invite people by email as a viewer or an editor, or turn on a link. People with access see changes live; viewers can read but not change the project.

Deleted projects wait in the Trash for 30 days. Open Trash on your dashboard and restore it. After 30 days, or after you choose “delete forever”, it is gone.

Yes. Projects can be exported and imported as .json. On Student and the paid plans you can also export a project with its full worked-out steps as a LaTeX document.

Room, never the maths. Every plan has the units engine, step-by-step solutions, graphs and collaboration. Plans differ in how many projects, elements per project, editors per project and saved versions you get. See Pricing for the exact numbers.

Business is $22 per person per month. The person who buys it is the team owner; they can buy as many seats as they need and appoint admins. Owners and admins add people by email under Team in the sidebar. Each person keeps their own account, dashboard and projects and gets the Business plan while they hold a seat; the team can’t open anyone’s own projects. Everyone on the team also shares a Team pool in the sidebar, where you can all open, edit, organise and add projects and folders together. Remove someone and they go back to their own plan with nothing deleted. The owner can add or remove seats any time from the Team page, and can hand the team to another member, who buys their own Business plan and accepts; the previous owner’s subscription then ends with its current period.

Open Settings, then Email and sign-in, then Change email. We send a link to the new address, and your address changes once you open it (we may also ask you to confirm from your current address). If the new address ends in .edu you get the Student plan from that moment; if you move away from a school address, you move to Hobby. Nothing is deleted, but projects over Hobby’s limits are locked until you upgrade.

Yes, both. In Settings, under Email and sign-in, you can set a password if you signed up with Google, and connect Google if you signed up with a password. You can disconnect Google once you have a password, so you can never be locked out.

Sign up with your school email address (it must end in an accepted academic domain, currently .edu) and confirm it. The plan is applied automatically and lasts a year. Before it ends we ask you to reconfirm by opening a link we send to your school address; if you don’t within ten days of the year ending, you move to Hobby. Nothing is deleted, and you can reconfirm later to get Student back.

Hobby, Student, Plus and Pro are for personal, educational and other non-commercial use. A business, an employer or paid client work needs Business. This is set out in our Terms.

Nothing is deleted, but projects over your new plan’s limits are locked: your most recently edited ones stay open and the rest can’t be opened until you upgrade again or delete projects to get back under the limit. You can always download all your data from Settings, locked projects included.

Open Settings, then Plan and billing, then Manage billing. You can update your card, see invoices, change plan and cancel there. Cancelling takes effect at the end of the period you have paid for.

Yes, within 14 days of your first payment for a paid plan, no questions asked. A yearly renewal you did not mean to keep can be refunded within 7 days of the charge. Email support@mathora.app from your account address. Cancelling stops future renewals but does not refund the current period. The details are in our Terms.

We show a notice in the app, and Stripe retries the card and emails you. Update your card from Manage billing. You keep your plan while Stripe is still retrying.

Open Settings, then Support and account, then Download data. You get your profile, folders and projects as one JSON file.

Open Settings, then Support and account, then Delete account. This permanently removes your account and everything you own. If you have a paid plan, the subscription is cancelled first, so you are not charged again. Stripe keeps the invoices it is required to retain.

Please tell us. Use the feedback button (or Settings, then Support and account, then Contact us) and choose “Something’s broken or a result looks wrong”. Include the formula and what you expected so we can reproduce it. Mathora is a calculation aid: check results that matter before relying on them.
