Terms of use

Last updated 12 October 2026

These terms apply to the Hey Dolly app and website ("Hey Dolly", "we"), run by Gokul G Nair, India. By using Hey Dolly you agree to them.

Your account

• Keep your sign-in details to yourself. An account is used on one phone at a time.
• You are responsible for the cards and notes you add. Do not add material you have no right to use, or anything unlawful or abusive.
• You can delete your account at any time; see the privacy policy for what happens to your data.

Pro, credits and payments

• Pro and credit packs are sold in the app through Google Play, at the prices shown there and on the pricing page. Pro renews automatically until you cancel it in Google Play.
• Pro includes 25,000 credits each month; unused monthly credits do not carry over. Credits from packs never expire and are used after the month's credits.
• Institution plans are agreed with the institution and paid through Razorpay or by bank transfer, as described on the pricing page. If a renewal is not paid within 7 days of its due date, the institution's AI features, natural voices and new members pause until it is paid; revision keeps working.
• Refunds and cancellation are covered by the refund and cancellation policy.

Institutions

When you join an institution, its head and teachers can see your progress on the material it gives you, as the privacy policy explains. The institution decides who joins and may remove members. Material made for an institution stays with it.

AI and voices

AI-made cards and explanations can contain mistakes; check them before relying on them. Natural voices and AI depend on third-party services and may be unavailable at times.

Our service

We work to keep Hey Dolly available and your data safe, but provide it "as is", without guarantees of results in exams. To the extent the law allows, our liability is limited to the amount you paid us in the 12 months before a claim. We may change features or these terms; for significant changes we will tell you in the app.

Law

These terms are governed by the laws of India. Contact us first with any complaint: heydolly.support@gmail.com.
