Nikatru is a one-person software business in Chennai, India — a proprietorship of Rajasekar Selvam. The person who writes the apps is the person who answers support. Write in English or Tamil.

What to put in your message

The more of this you include, the more likely the first reply solves it rather than asking questions back:

Which app, and where you are using it — the web app, Android, iOS, Windows or macOS.
Your device and version — for example "Pixel 7, Android 15" or "Chrome on Windows 11". The app version is shown on its settings or about screen.
What you did, what happened, and what you expected instead. The exact steps matter more than the description — if we can reproduce it, we can usually fix it.
A screenshot, if anything is visible on screen. Please blank out anything you would not want us to see.
The email address on your account, if the problem is about signing in or about your data.
For a payment or refund — the order or transaction ID from your receipt, and who took the payment (Paddle, Razorpay, Apple or Google).

Please do not send us passwords, one-time codes, full card numbers, or any government identity number. We never ask for them and we do not need them to help you.

How quickly we answer

Support email — we reply within 2 business days.
A formal complaint or grievance — our Grievance Officer acknowledges within 48 hours and resolves within 30 days.

Common questions

Can I buy anything yet?

No. Paid checkout is not open on nikatru.com and we have taken no payments. Our apps are free to use today. When checkout opens, international purchases will be handled by Paddle as merchant of record and purchases in India through Razorpay; the terms are already published on our Terms, Refunds and Shipping & Delivery pages.

I paid and the purchase has not appeared

Sign out and back in with the exact email address you used at checkout — that is the usual cause. If it is still missing 30 minutes after payment, email us with the order ID. Full detail on the Shipping & Delivery Policy page.

How do I get a refund or cancel?

See the Refund & Cancellation Policy. It sets out the 30-day money-back guarantee, the India timeline, and how store purchases are handled.

How do I delete my account and my data?

You can delete your account and everything in it from inside the app, or by following the steps on our Delete your account and data page. That page is the route for a deletion request whether or not you can still sign in.

What do you do with my data?

Our Privacy Policy lists what we collect, why, who else sees it, how long we keep it and how to have it erased. Each app also has its own short notice — linked above — saying what that specific app collects.

Do I have to be an adult?

Yes. Our apps and this site are for people 18 or older. See the Terms of Service.

If we have not put it right

If a support reply has not resolved your problem, escalate it as a grievance. Our Grievance Officer is Rajasekar Selvam, Proprietor — [email protected], +91 94984 98011. Write "Grievance" in the subject line, and include what you asked for, when, and what happened. He acknowledges within 48 hours and resolves within 30 days. The same route covers privacy, data-protection and consumer complaints; the full block is on the Contact page.

If a privacy complaint is still unresolved after that, you may take it to the Data Protection Board of India under the Digital Personal Data Protection Act, 2023. A consumer complaint may be taken to the consumer forum with jurisdiction, or through the National Consumer Helpline.
