SutranetTowerPrivacy Policy
Last updated: 11 October 2026
This Privacy Policy explains how Sutranet (operated by Oruganti Vamsi Krishna, an individual carrying on business under the name and style of "Sutranet"; "we", "us", "our") collects, uses, and protects personal data when you use SutranetTower and our related free tools such as the Sutranet Graph Digitizer (together, the "Service") at www.sutranet.co.in. We are the data fiduciary for this data under India's Digital Personal Data Protection Act, 2023 ("DPDP Act").
1. Data We Collect
| Category | What | Why |
|---|---|---|
| Account data | Email address; display name and basic profile if you sign in with Google; an assigned user ID and account role/quota. | To create and manage your account, authenticate you, enforce usage limits, and send you occasional service updates (see section 2). |
| Content you provide | Tower definitions, section and bracing inputs; the analyses you choose to save, with their inputs and the reports generated from them; and any bracing patterns or mount entries you save to your library. | To run the analysis you request and to save your work. |
| Technical data | IP address, browser type, request timestamps, and server logs. | Security, debugging, and reliable operation of the Service. |
| Local storage | An authentication token and your display-unit preference (SI or US), stored in your browser's local storage. | To keep you signed in between visits and to remember your unit choice. These are not third-party tracking cookies. |
| Anonymous usage counts | Aggregate counts of anonymous events — a page view, and a "used" signal (a free tool was used, or the app was opened from the home page) — for our home page and our free client-side tools. No cookies, no identifiers, and never the images, charts or data you work on. | To measure whether the site and a free tool are genuinely useful before we invest further in them. |
We do not intentionally collect sensitive personal data, and we ask that you do not submit any.
Free client-side tools. Some tools we offer — such as the Sutranet Graph Digitizer — run entirely in your browser. The images, charts and data you load into them are processed on your own device and are never uploaded to us or to any third party. The only information such a tool sends is an anonymous usage signal (that a page was viewed, and that the tool was used at least once), and only when you use the tool on our website — a copy opened as a local file sends nothing. This signal contains no personal data and none of your content.
2. How We Use Your Data
- to provide, operate, secure and improve the Service;
- to authenticate you and maintain your account, role and usage quota;
- to run the analyses you request and store the inputs and results associated with your account;
- to understand whether our free tools are useful, using anonymous aggregate usage counts that contain no personal data;
- to communicate with you about your account or the Service. This includes occasional emails to registered users about significant updates, such as a new design standard, new features or training material. You can opt out of these update emails at any time by replying to one or by writing to support@sutranet.co.in; emails needed to operate your account, such as a password reset, are not affected;
- to comply with legal obligations and enforce our Terms & Conditions.
3. Legal Basis
We process your personal data on the basis of your consent (given when you create an account and use the Service) and, where applicable, to perform our contract with you and for our legitimate interest in operating a secure Service. You may withdraw consent at any time by closing your account (see Section 7).
4. Third-Party Services (Processors)
We rely on a small number of trusted providers to run the Service. Data may be processed by them on our behalf:
- Google Firebase Authentication & Cloud Firestore — to authenticate accounts (including Google Sign-In) and store account role/quota. If you choose "Continue with Google", your browser loads Google's sign-in software directly from Google's servers. Governed by Google's privacy policy.
- Google Cloud Platform — hosting infrastructure for the Service.
- Anthropic (Claude API) — only when AI guidance features are used, the relevant inputs (e.g. a bracing pattern, your tower inputs or an analysis summary, and any question you type) may be sent to Anthropic's API to generate guidance. No account credentials are sent. If this feature is not enabled, no data is sent to Anthropic.
Some of these providers may process data on servers outside India; where they do, we rely on the provider's safeguards and applicable law for such transfers.
5. Data Sharing
We do not sell your personal data. We share it only with the processors above, or when required by law, or to protect the rights, safety and security of Sutranet, our users, or the public.
6. Data Retention
We retain account data for as long as your account is active. An analysis you do not save is kept only until your next run replaces it. Analyses you save (their inputs and reports), saved bracing patterns, saved mount entries and account records are stored on our server until you delete them or close your account; your oldest saved analyses may be removed automatically when your storage allowance is exceeded. Routine backups of the server may retain a copy for a limited period after deletion. Server logs are retained for a limited period for security and troubleshooting.
7. Your Rights
Subject to the DPDP Act and applicable law, you may:
- access and obtain a summary of the personal data we hold about you;
- request correction or updating of inaccurate data;
- request erasure of your data and closure of your account;
- withdraw consent to processing;
- nominate another individual to exercise your rights in the event of death or incapacity.
To exercise any of these, contact us at support@sutranet.co.in.
8. Security
We use reasonable technical and organisational measures, including transport encryption (HTTPS) and access controls, to protect your data. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.
9. Children
The Service is intended for professional use and is not directed to children. We do not knowingly collect personal data from children. Where required, processing of a child's data will only occur with verifiable parental/guardian consent as mandated by the DPDP Act.
10. Changes to This Policy
We may update this Policy from time to time. Changes take effect when posted, indicated by the "Last updated" date above. Material changes will be brought to your attention where appropriate.
