Lock Ten Studio LLC ("we", "our", "us") operates Walkthrough, a mobile app that helps custom home builders capture voice memos and photos during job-site walkthroughs, transcribe and format them into reports, and route the output to the builder's existing tools.
This Privacy Policy describes what information we collect, how we use it, who we share it with, and the choices you have.
Account information. When you create an account, we collect:
Walkthrough content. When you use the app, we collect:
Cloud storage tokens. If you connect Dropbox or Google Drive, we store the OAuth access and refresh tokens needed to write files to your storage. These tokens are encrypted at rest using AES-256-GCM.
Operational data. To run the service, we collect:
Weather and location. When you add a project address, we convert it to map coordinates using the US Census Bureau geocoding service. When you use daily logs, we send those coordinates (never the address itself) to a weather service to fill in the day's weather. Neither service receives your name, your client's name, or anything from your reports.

Each provider operates under its own privacy policy. We recommend reviewing them if you have concerns.
We keep your content only while your account is active, so the app can show you your past work. We do not keep it indefinitely after you leave.
When you delete your account, we remove your personal data and walkthrough content within 30 days. We may keep aggregated, non-identifying analytics that cannot be traced back to you.

support@lockten.aiIf you live in California, the EU, the UK, or another jurisdiction with broader data-protection rights, you may have additional rights under local law (such as the right to portability or the right to object to certain processing). Contact us and we will honor them.
We use standard practices:
No system is perfectly secure. We commit to investigating any breach and notifying affected users within 72 hours of confirmed discovery.
Walkthrough is intended for use by adults working in the construction industry. We do not knowingly collect information from anyone under 18. If you believe we have collected information from a minor, please contact us and we will delete it.
We may update this Privacy Policy from time to time. We will post the new version at this URL and update the "Last updated" date at the top. For material changes, we will notify active users via email at least 30 days in advance of the change taking effect.
