Referral program

Referral rules

Recommend Syllonaut to colleagues and get bonus lessons for everyone who actually starts using it.

Who can take part

Teachers with an individual account (Free, Teacher or Teacher Pro) get a personal referral link on the Subscription page.
Administrators and members of a school or organization account do not take part and have no referral link.
You share the link yourself. Syllonaut sends no invitations and does not ask for your colleagues’ email addresses.

A colleague signs up through your link, or enters your code in the optional "Referral code" field during registration.
Each new account can have at most one referrer, and it cannot be changed after registration.
The code is taken only from the link or the registration form; Syllonaut stores no cookie or other browser data for it.

Within 60 days of registering, the invited colleague must either subscribe to a paid individual plan (Teacher or Teacher Pro), or verify their email and teach an ended live lesson in which at least 5 different participants submitted at least one individual answer.
For the live lesson route, the invited colleague must not share any device with you (for example the same browser used for both accounts).
Only the referrer is rewarded; the invited colleague receives nothing.
Referrals are evaluated automatically about once an hour. If the conditions are not met within the deadline, the referral expires without a reward.

For each qualified colleague you get 1 bonus lesson (a bonus AI lesson generation), valid for 12 months from the day it is credited.
Bonus lessons are used only after the monthly lesson limit of your plan runs out, starting with those that expire first. A failed generation does not use a bonus lesson.
Bonus lessons are not a discount, cannot be exchanged for money and cannot be transferred to another account.
Bonus lessons can be used only while your account is individual. As a member of a school or organization they stay frozen; their validity is not extended.
Other limits of your plan, including the Free plan limits per device, still apply.

At most 3 rewards per calendar month (UTC) and at most 10 rewards in total.
A referral that qualifies after a limit has been reached is recorded without a reward; it is not carried over to a later month.

No reward is granted when you refer your own account, when the colleague registers on a device you use, when the email addresses are the same (including variants of one Gmail address), or when the colleague registers with a disposable email address.
Syllonaut may withhold or remove a reward obtained by circumventing these rules.

To run the program, Syllonaut records which account referred which, and a one-way hash of the device identifier used to prevent misuse. You never see the names or email addresses of the colleagues you referred, only the numbers.
The link between the accounts is deleted at the latest 12 months after the referral closed, or after the reward expired; details are in the Privacy Notice.

Syllonaut may change or end the program. Bonus lessons already credited remain valid until they expire.
