DeckNotes is a tool you point at a Google Slides deck. It reads the deck, asks a panel of AI reviewers to comment on it, and writes the panel’s feedback back into your file as native Slides comments. To do that, we need a few pieces of information about you and your deck. We collect them, use them for that purpose, and stop.

When you sign in with Google, we receive your email address, your name, and your profile picture URL. We use this for one thing: identifying which DeckNotes account belongs to you. We don’t ask Google for access to your Drive, your Gmail, your contacts, or anything else. The OAuth scopes we request are openid, email, and profile.

We store your email and name in our database so you can sign in again later and see your decks. We do not share your email with anyone. We don’t put you on a marketing list. We don’t sell or rent contact information — ever.

We don't store a copy.

When you point DeckNotes at a Slides file, we read the slides at review time and let them go. We don't keep a copy of your presentation on our servers. We keep the metadata — file ID, who ran the review, when, which reviewers participated — because we need it to count your readings and show you a history. We don't keep the contents.

Prompts are anonymized.

To generate feedback, slide content is sent to Anthropic's Claude. Before we send it, we strip metadata that would identify you, your company, or the deck — your name, the file title, your email. Claude sees the words on your slides and not much else. Anthropic's API doesn't retain content for training in our configuration.

Comments live in your Drive.

Reviewer feedback is written as native Google Slides comments in the file you already own. Delete the file, delete the conversation. Revoke DeckNotes' access in Google, and we lose our handle on the file. Your Drive is the system of record; we're a participant.

To deliver the service, we route data through a small number of vendors. Each one only sees the data it needs:

Anthropic

Slide content is sent to Anthropic’s Claude API to generate reviewer feedback. We strip identifying metadata before sending. Anthropic’s API does not retain content for training in our configuration.

Google

We sign you in via Google OAuth and post reviewer feedback as comments on your Google Slides files. Google’s privacy practices govern your Google account itself.

Mailgun

Transactional email (sign-in links, share notifications) is delivered via Mailgun. They process your email address to deliver messages and don’t use it for anything else.

Render

Render hosts the application and its database. Your account record and the metadata we keep about your decks live there.

We use a single session cookie to keep you signed in. It expires when you sign out or after a period of inactivity. We don’t use third-party advertising or tracking cookies. We don’t embed analytics scripts that follow you across the web.

You can, at any time:

• Sign out and stop using the service.
• Revoke DeckNotes’ access to your Google account at myaccount.google.com/permissions. When you do, we lose our handle on your Drive files.
• Email hello@decknotes.app and ask us to delete your account and the metadata associated with it. We’ll do it within seven days and confirm by email.
• Ask for a copy of the data we hold about you. Same email; same turnaround.

If you’re a resident of California, the EU, the UK, or another jurisdiction with specific data-protection rights, the same address applies. We honor deletion and access requests regardless of where you live.

DeckNotes is not directed at children under 13. We don’t knowingly collect data from anyone in that group. If you believe a child has signed up, write to us and we’ll delete the account.

If we update this policy in a way that meaningfully changes what we do with your data, we’ll send a heads-up to your account email before the change takes effect. The current version always lives at this URL with the “Last updated” date at the top.
