Seisaku Studio is operated by Mentis Vision LLC ("we", "us"). It turns recorded video and audio into an edited master cut and related written assets, and can publish those assets to social accounts you connect. This policy explains what we collect, why, who we share it with, and how you remove it.
| Data | Why we hold it |
|---|---|
| Name, email address, and optionally your role and business name | To create your account and identify you as the author of content you publish. |
| Authentication identifier from your sign-in provider | To sign you in. We never receive or store your password. |
| Recordings you upload, and transcripts derived from them | To produce the master cut, captions, clips and written assets you asked for. |
| Your brand kit — tone of voice, colours, positioning, banned words | To shape generated content to your brand. |
| Access tokens for social accounts you connect | To publish on your behalf, only when you ask us to. |
| A record of what was published, where, and when | To show you your publishing history. |
| Diagnostic error reports | To find and fix faults. Reports are stripped of credentials before they leave our systems. |
We do not collect special category data, we do not use your recordings for advertising, and we do not sell personal information.
We use the following providers. Each receives only what its function requires.
| Provider | What it receives |
|---|---|
| Google Firebase Authentication | Your email address and sign-in identifier. |
| Google Gemini API | Audio and text you submit for transcription, analysis and content generation. |
| Amazon Web Services (S3) | Media files you upload. Stored in a private bucket in the US West (Oregon) region. |
| Neon (PostgreSQL) | Account details, brand kit, publishing history and encrypted access tokens. |
| Sliplane | Application hosting. |
| LinkedIn, Meta, Google/YouTube, Canva | Only the content you explicitly choose to publish or sync, and only to accounts you have connected. |
| Descript, HeyGen | Optional. Used only if you supply credentials for them. |
| Sentry | Error diagnostics, with credentials and request bodies redacted. |
When you connect an account, the provider issues us an access token scoped to the permissions shown on their consent screen. We use those permissions only to publish content you have composed and confirmed. We do not read your feed, message your contacts, or post without an explicit action from you.
Access tokens are encrypted with AES-256-GCM before being written to our database, so a copy of the database alone does not grant access to your accounts. You can disconnect any account at any time, which deletes the stored token.
Where you grant Google Drive or YouTube permissions, we use them solely to read media files you select and to upload videos you choose to publish. Our use of information received from Google APIs adheres to the Google API Services User Data Policy, including its Limited Use requirements. We do not use Google user data for advertising, and we do not allow humans to read it except where required for security, to comply with law, or with your explicit consent.
You can access, correct, export or delete your data. Under the GDPR you may also object to or restrict processing, and lodge a complaint with your supervisory authority. Under the CCPA you may request disclosure and deletion, and we do not sell or share personal information as those terms are defined there.
To exercise any of these, use the deletion page or email sang@mentisvision.com. We respond within 30 days.
Traffic is encrypted in transit. Access tokens are encrypted at rest at the application layer, separately from the database's own encryption. Every API route requires an authenticated session, and your data is scoped to your account.
We process data in the United States. If you are in the UK, EEA or Switzerland, your data is transferred there under appropriate safeguards.
The service is not directed to anyone under 16, and we do not knowingly collect their data.
We will update this page and change the date above when this policy changes. Material changes will be notified by email.
