Privacy Policy
This Privacy Policy describes how KVSHVL (operated by Kushal Samant Architects, "we", "us", or "our") collects, uses, and protects information when you use kvshvl.in and related web applications we publish on subdomains of kvshvl.in (collectively, the "Services").
By using the Services, you agree to the collection and use of information as described in this policy.
1. Who we are
KVSHVL is an architecture practice and technology platform operated by Kushal Samant Architects. The primary website is kvshvl.in. Individual tools may be hosted on subdomains (for example, checkyourdrawings.kvshvl.in).
2. Information we collect
Account and authentication
When you sign in to a Service that requires an account, we may collect:
Name and email address from your identity provider (for example, Google sign-in via Supabase Auth).
A stable user identifier and session tokens needed to keep you signed in.
Subscription status linked to your account in our platform database.
We do not ask for a separate KVSHVL password when you use Google sign-in.
Subscription and billing
If you purchase or hold a paid KVSHVL subscription, we store subscription tier, status, and related account metadata in our platform database. Payment processing may be handled by third-party payment providers; we do not store full card numbers on our servers.
Usage and analytics
On kvshvl.in, we use Google Analytics to understand aggregate traffic and how visitors use the site. Analytics data may include pages viewed, approximate location (derived from IP), browser type, and referral source.
Individual applications may use similar analytics for product improvement. We do not use analytics to inspect the contents of files you upload for processing.
Information you provide directly
You may contact us by email or phone. We retain correspondence needed to respond to enquiries and maintain business records.
3. How we use information
We use collected information to:
Provide, operate, and improve the Services.
Authenticate users and enforce subscription access where applicable.
Respond to support requests and communicate about the Services.
Monitor security, prevent abuse, and comply with legal obligations.
Understand aggregate usage through analytics.
We do not sell your personal information.
4. Check Your Drawings
Check Your Drawings compares two architectural drawing PDFs and returns a coordination overlay.
Free compare (no sign-in): You may upload two PDFs without creating an account. Files are transmitted to our processing server for comparison only.
Paid batch features: Batch compare and ZIP export require sign-in and an active KVSHVL subscription.
File handling:
Uploaded PDFs are processed in memory and on temporary server storage to produce comparison outputs.
Generated PNG and PDF outputs are stored on the processing server for up to 24 hours, then automatically deleted.
We do not store your drawings or comparison outputs in our platform database or long-term cloud storage. You are responsible for downloading deliverables to your own systems.
We do not use your uploaded drawings to train machine-learning models.
If you do not want files on our servers, do not upload them. Use the free tier only with non-sensitive test files if you are evaluating the tool.
5. Third-party services
We rely on third-party providers to run the Services, including:
Google — Sign-in (OAuth), analytics.
Supabase — Authentication infrastructure.
Hosting providers (e.g. Vercel, Render) — Application and API hosting.
These providers process data according to their own privacy policies and our agreements with them. When you sign in with Google, Google’s consent screen and policies also apply.
6. Data retention
Account and subscription records: Retained while your account is active and as needed for billing, disputes, and legal compliance.
Check Your Drawings uploads and outputs: Deleted from processing servers within approximately 24 hours, as described above.
Analytics: Retained according to Google Analytics configuration and our operational needs.
Email correspondence: Retained as long as reasonably necessary for the purpose it was collected.
7. Your rights and choices
Depending on applicable law, you may have the right to access, correct, or delete personal information we hold about you, or to object to certain processing.
To exercise these rights, use the contact details at the end of this policy. We may need to verify your identity before fulfilling a request.
You can limit analytics on kvshvl.in by using browser privacy settings or opt-out tools offered by Google.
8. Security
We use reasonable technical and organizational measures to protect information, including encrypted transport (HTTPS) and access controls on production systems. No method of transmission or storage is completely secure; we cannot guarantee absolute security.
9. Children’s privacy
The Services are not directed to children under 18. We do not knowingly collect personal information from children. If you believe a child has provided us personal information, contact us using the details at the end of this policy and we will take appropriate steps to delete it.
10. International transfers
Our service providers may process data in countries other than your own. By using the Services, you consent to such processing subject to applicable law and the safeguards described in this policy.
11. Changes to this policy
We may update this Privacy Policy from time to time. The "Last updated" date at the top will change when we do. Continued use of the Services after changes constitutes acceptance of the revised policy.
