Privacy policy
Last updated: 13 November 2026
This policy explains how Advanced Computer System, 223/3 GT Road West Lane, Bardhaman, West Bengal (“ACS”, “we”) handles personal data for Kaunter, in line with the Digital Personal Data Protection Act, 2023.
What we collect
- Enquiries and trials: your name, mobile number, shop name, city, type of shop, number of shops, optional email and message, and where you heard about us (for example an ad or a referral link).
- Account: owner name, mobile, email(s) for reports, stores, licence and payment records (amount, UPI reference, invoice).
- Shop data you create in the app: bills, items, stock, accounts, staff names. Customer names or phone numbers are stored only if you enter them.
- Technical: a hashed (not readable) form of your network address to stop spam and abuse, and the time your phone last synced.
Why we use it
- To provide the app, licences, sync, backups, owner dashboard and emails you asked for.
- To contact you about your enquiry, trial, setup, renewals and support.
- To prevent fraud and misuse, and to keep accounting and tax records.
We do not sell your data and do not use your shop data for advertising.
Where it is stored
Shop data is stored on your phone and in our cloud database (Cloudflare), which may process data outside India. Backups go to your own Google Drive, and Kaunter can only access the files it creates there. Emails are sent through an email delivery service. These providers act on our instructions.
How long
Shop changes are kept in the cloud for about 35 days after they are safely backed up to your Drive. Account and payment records are kept as long as the law requires. Enquiries that do not become customers are kept for up to 2 years, unless you ask us to delete them sooner.
Your rights
You can ask to see, correct or erase your personal data, withdraw consent for calls or messages, or nominate someone to act for you. Write to the grievance contact below; we reply within 30 days. If you are not satisfied, you may approach the Data Protection Board of India.
Security
Connections are encrypted (HTTPS). Phone links and owner links are random secret keys stored only in hashed form. Google access is stored encrypted. The ACS Console is protected by a secret key and a login code. No system is perfectly secure, so please keep your PINs and owner link private.
