Privacy Policy

Last updated September 15, 2026

Persell (“Persell”, “we”, “us”) is a personal selling assistant for small businesses, available at persell.ai. This policy explains what information we collect when you use Persell, how we use it, who we share it with, and the choices you have. If you have questions, email andy@deeptrace.com.

Information we collect

Account information. When you create an account we collect your name, email address, and authentication details. Sign-in is handled by Clerk, our authentication provider.

Google account data. Persell works by connecting to Google services you choose to authorize. You decide which services to connect, and you can disconnect them at any time. Depending on what you enable, Persell may access:

• Gmail (scope gmail.modify): we read messages, threads, labels, and attachment metadata in your mailbox to build your business wiki and to find conversations that need a reply. We create drafts and send messages only when you review and approve a specific action in Persell. We do not delete messages.
• Google Calendar (scopes calendar.readonly and calendar.events): we read your calendars and events to prepare you for upcoming meetings, and we create or edit events only when you approve a specific action.
• Google Sheets (scope spreadsheets): we read and write individual cells in spreadsheets you point Persell at, so it can update product and order information you keep there. Writes happen only when you approve them.
• Basic profile (scopes openid and email): your Google account email address, used to label the connection and confirm the right account is linked.

Other connected services. If you connect Shopify or another commerce platform, we access your catalog, products, and orders through that platform’s API under the permissions you grant there.

Content you provide. Messages you send to Persell, instructions, and edits you make to drafts.

Usage and technical data. Standard server logs such as IP address, browser type, pages visited, and timestamps, used for security and to keep the service running.

How we use information

• To build and maintain your private business wiki from the email, calendar, and store data you connect.
• To prepare draft replies, listing changes, meeting briefs, and other suggested actions for your review.
• To carry out actions you explicitly approve, such as sending an email, saving a draft, creating a calendar event, or updating a spreadsheet cell.
• To operate, secure, debug, and improve Persell.
• To communicate with you about your account and the service.

We do not use your Google user data to serve advertisements, and we do not sell it.

AI processing

Persell uses large language models to summarize your data and prepare drafts. To do this, relevant excerpts of your connected data (for example, the text of an email thread you asked Persell to reply to) are sent to our model providers, currently accessed through OpenRouter. These providers process the data only to return a response to Persell and are contractually prohibited from using it to train their models. We do not use your Google user data to train generalized AI or machine-learning models.

Google API Services User Data Policy

Persell’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. In particular:

• We only use Google user data to provide and improve the user-facing features of Persell described above.
• We do not transfer Google user data to third parties except as necessary to provide those features, to comply with law, or as part of a merger or acquisition with notice to you.
• Humans do not read your Google user data unless you give us explicit permission for a specific support request, it is required for security or legal reasons, or the data has been aggregated and anonymized.
• We do not use Google user data for advertising, and we do not sell it.

How we share information

We share information only with service providers that help us run Persell, each bound to use it solely on our behalf:

• Render — application hosting and our managed PostgreSQL database.
• Clerk — account authentication.
• OpenRouter and the model providers it routes to — AI processing as described above.
• Google and Shopify — the platforms you connect, when Persell reads from or writes to them on your behalf.

We may also disclose information if required by law, to protect the rights and safety of Persell and its users, or in connection with a business transfer.

How we protect information

• All traffic to and from Persell is encrypted in transit with TLS.
• Google and Shopify access tokens are encrypted at rest with AES-256-GCM using keys stored separately from the database.
• Data is isolated per account. Every read and write is checked against the signed-in owner.
• OAuth flows use PKCE, single-use state, and session binding to prevent connection hijacking.
• Access to production systems is limited to the people who operate Persell.

Retention and deletion

We keep your connected data and the wiki derived from it for as long as your account is active so Persell can keep working for you. When you disconnect a Google account in Settings, we revoke our access token with Google and stop reading from that account. When you delete your Persell account, or ask us to at andy@deeptrace.com, we delete your account data, stored tokens, and derived content within 30 days, except for records we must keep for legal or security reasons. You can also revoke Persell’s access at any time from your Google Account permissions page.

Your choices

• Choose which Google services to connect during setup, and change them later in Settings.
• Review every prepared email, calendar, spreadsheet, and store action before it runs. Nothing is sent or changed without your approval.
• Disconnect any connected account, or delete your Persell account, at any time.
• Request a copy of your data, or its correction or deletion, by emailing us.

Children

Persell is for businesses and is not directed to children under 16. We do not knowingly collect information from children.

International users

Persell is operated from the United States and your data is processed there. By using Persell you consent to this transfer and processing.

Changes to this policy

We will post any changes on this page and update the date at the top. If a change materially affects how we handle Google user data, we will notify you by email before it takes effect.
