Privacy Policy

1 Who we are

Certain Systems, a proprietorship in Bangalore, Karnataka, India, provides engineering, embedded-systems and IT software services and runs certainsystems.in. Under the Digital Personal Data Protection Act, 2023 (DPDP Act) we are the Data Fiduciary: we decide why and how your personal data is used.

• Proprietor: Gangatharan J
• GSTIN: 29ADPPG1805P1Z2
• Privacy contact: [email protected] (details in section 13)

2 What we collect

We do not ask for passwords, OTPs, card numbers or government ID numbers on WhatsApp or e-mail. Please do not send them.

3 Why we use it, and on what basis

4 Your consent and how to change it

Withdrawing consent is as easy as giving it. Send these words to our WhatsApp number +91 72599 74251; you get a confirmation each time:

For e-mail, use the unsubscribe link in our mails or write "unsubscribe" to [email protected]. For the website, use Cookie settings. A withdrawal applies from then on; it does not undo what was lawfully done before. We keep a record of each consent and withdrawal, with the version of this policy shown at the time, as proof that we respected your choice.

5 Who processes your data for us

We never sell or rent your personal data. These service providers (Data Processors) handle it only to provide their service to us:

We also disclose data when Indian law, a court or an authorised government agency requires it.

6 Data outside India

Meta, Google, Cloudflare and Telegram may store or process data on servers outside India. The DPDP Act allows this except to countries the Government of India restricts; we will follow any such restriction.

7 Where we keep it and how we protect it

• Our business system (ERPNext) and its database run on a self-hosted server at our premises in Bangalore.
• All connections are encrypted (TLS). Only authorised people can open our business systems, after a sign-in with a one-time code.
• Messages from WhatsApp are accepted only when Meta's digital signature on them is valid.
• Backups are encrypted and kept on a separate disk.
• If a personal data breach happens, we will inform the affected people and the Data Protection Board of India as the DPDP Rules require.

8 How long we keep it

9 Your rights

• Access: a summary of the personal data we hold about you, what we do with it and with whom we share it.
• Correction and update: fix or complete your data.
• Erasure: delete your data. Records the law makes us keep (such as GST invoices) are kept but used for nothing else, and we tell you what was kept and why.
• Withdraw consent at any time (section 4).
• Grievance: complain to us about how we handle your data.
• Nominate a person who may use these rights for you in case of death or incapacity.

How: send DELETE MY DATA (or your request) on WhatsApp to +91 72599 74251, or e-mail [email protected]. A request from your own WhatsApp number or e-mail address is treated as coming from you; otherwise we may ask you to confirm. We acknowledge within 48 hours and answer within 30 days.

If you are not satisfied with our answer to a grievance, you may complain to the Data Protection Board of India.

10 Children

Our services are for businesses and adults (18 years or older). We do not knowingly collect data from children. If you believe a child has sent us personal data, tell us and we will delete it.

11 Cookies on this website

• Necessary: your cookie choice, stored in your browser, and security checks by Cloudflare. Always on.
• Analytics (only if you allow): Google Analytics cookies to count visits and see which pages are used.

We ask once and remember your choice in your browser. We ask again only if we change what we use cookies for. Change your choice at any time: Cookie settings.
