Who we are
Rimi Lab (rimilab.com and its lab sites) is run from Bengaluru, Karnataka, India. You can reach us at [email protected].
The labs are free
The lessons, labs and tools are free to use for learning. They are provided as they are, without any promise that they are complete or free of errors. They are teaching material, not professional, financial, legal or career advice.
What you can buy
Support is a voluntary payment, once or every month, that helps keep the labs free. Some amounts come with downloadable workbooks, as the support page lists: Starter extras (₹499), one series complete (₹699) and everything released so far (₹999), all paid once; Supporter (₹199 a month) and All the extras (₹499 a month). A one-time payment covers what is listed on the day you pay. The one series option also covers that series' later parts. Prices are in Indian rupees. Payments are processed by Razorpay.
How you may use a workbook
A workbook is for your own learning, on your own devices. Please do not resell it, share the file publicly or upload it elsewhere. Teachers and teams who want to use workbooks with a group can write to us for a licence.
Monthly support
Monthly support renews every month until you cancel it. You can cancel at any time using the link in Razorpay's emails, or by writing to us. Nothing is charged after you cancel. Everything already sent to you stays yours. Parts released after your last paid month are not sent. Supporter rewards (at 3, 6 and 12 months) count paid months in a row.
Changes
We may update these terms. The date at the top shows the latest version. Purchases are governed by the terms in force when you paid.
Law
These terms are governed by the laws of India. Any dispute is subject to the courts of Bengaluru, Karnataka.
