About COLOSSALES

Colossales adds a Kanban CRM directly inside Gmail. Sort your conversations into columns, leave internal notes, set reminders, and (with Pro) manage a sales pipeline — without opening another tab. Salespeople already live in their inbox. Colossales attaches the card, status, comment, and reminder directly to the Gmail thread. No copy-pasting into a separate CRM. One specific use case: a Kanban CRM inside Gmail, with data stored in your Google Sheets. This is not a Google Workspace Marketplace add-on: it is a Chrome Manifest V3 extension. FEATURES • TODO Board (Free): To Do, In Progress, Waiting, Done — or your own columns. Each card is a real thread (inbox, sent, archived) or a manual card (call, trade show, lead outside email). • Internal comments attached to the thread. They are never sent to the customer. • Google Tasks reminders, also visible in Google Calendar depending on your configuration. Included in Free. • Pro Pipeline: Prospect → Qualified → Proposal → Won, with amount / date / probability fields, companies, contacts (Google Contacts read access), history, Drive files, multi-thread deals, dual TODO + Pipeline boards (editable columns). • Deal Assistant (Pro, on click): Gemini summarizes and suggests; you decide whether to apply the suggestions. It does not send emails. Local Google AI Studio key. • Team Plan: Workspace seats, shared Sheets workbook, members assigned to a card, read-only sharing. DATA On the first Sync, a “Colossales CRM Data” workbook is created in your Drive. You own it. Scope: drive.file — only files created by Colossales or files you explicitly open. No Google password is stored. No resale of mailbox data. PLANS Pricing: https://www.colossales.com/tarifs/ Free: TODO board, comments, Tasks reminders, last 30 threads, manual cards. Pro: pipeline, dual board, companies, contacts, history, deal fields, multi-thread deals, statuses, Drive, assistant, extended sync. Team: everything in Pro per seat, shared Sheets, Workspace sharing. Stripe payments on colossales.com. No in-app purchase through the Chrome Web Store. License = Google OAuth email. INSTALLATION 1. Add Colossales to Chrome. 2. Open Gmail using the account associated with your license. 3. Click the Colossales icon in Gmail’s left rail. 4. Authorize Gmail, Sheets, Tasks, Contacts (Directory for Team admins). 5. Pin the extension. 6. Sync, then drag a card. Help: https://www.colossales.com/aide/ Support: https://www.colossales.com/support/ Privacy: https://www.colossales.com/confidentialite/ PERMISSIONS Details: see policy above. * identity / email: license. * storage: local settings. * Gmail: board and threads. * Sheets + Drive: CRM workbook. * Tasks: reminders. * Contacts read access: contacts panel. * Directory: Team seats. * colossales.com: subscription, sharing, install ping (version only). FAQ Board not showing? Go to chrome://extensions → make sure Colossales is enabled, reload Gmail, then reconnect OAuth. Access denied? In GCP Testing mode, only allowlisted testers can authorize the app. Removing a card from the board does not delete the email. Multiple inboxes: if they are visible in Gmail, Sync indexes them. Colossales: your pipeline, without leaving Gmail.
