Privacy Policy

* Sensitive payment information such as card numbers is handled directly by Paddle and is not stored by the Company.

• Service delivery: account management, running AI analysis, collaboration features
• Payment processing: credit purchases, subscription management (via Paddle), and telling the person who pays — and, on a team workspace, its admins — when a subscription payment fails
• Service improvement: error analysis, feature improvement (excluding business data)
• Legal obligations: compliance with applicable laws such as e-commerce regulations
• Team administration: showing a team workspace's owner and admins each member's usage from the team pool, per-seat limits and pool alerts, and the team activity log (including which team plans and costing sheets were opened)
• Security: signing out idle sessions after 30 minutes and keeping one active session per account
• Price history: recording why each price changed and why a price was confirmed, countered, dropped or reopened, so the plan owner keeps a lasting negotiation record

As a rule, we do not provide users' personal data to third parties. However, we share personal data with the following providers for service operation.

* The contents of files you upload (spreadsheets, PDFs, documents, photos) and your chat messages may be sent to Anthropic to run the analysis, and a question you type into AI search in Cost Sheets is sent with the names of your buyers, seasons, categories and materials so it can be turned into a search filter; short search text may be sent to OpenAI to find comparable references. Under both providers' API terms this data is not used for training.

Emails you ask us to send: when you send an order to your departments — and when an order that was sent is later revised, cancelled or reopened — we email the contacts you listed, including the order's attached files. Invitations go to the factory addresses you enter. You are responsible for having their permission to receive these emails.

† Google sign-in and Google Drive sync are optional and off by default. If you connect Drive, costing sheets and related files are copied into a folder in your own Google Drive at your request. On a team workspace, copies of team files go to one team folder in the owner’s Google Drive instead, and that folder is shared view-only with each active seat’s sign-in email through Google (so the owner and other seats can see who it is shared with); access is removed when a seat leaves.

Within a team workspace: if you accept a seat on someone else's Team, Scale or Custom workspace, your usage drawn from the team pool (in US dollars) and your team activity log entries (including which team plans and costing sheets you opened) are shown to that workspace's owner and admins. The team plans, masters and costing archive you work on there are shared with the workspace.

Price history: reasons and notes a factory gives when it submits a new costing version are provided to the buyer who invited it and stored as part of that buyer's data. A factory sees only the entries it wrote itself, never the buyer's entries or another factory's. The name (or, if no name is set, the email) of a buyer-side user who records a reason is shown to other users with access to that plan.

Where a company uses GRAINSIFT through a team workspace, the workspace owner decides who is invited and uses the usage view and activity log to administer the team. For that team data, the Company processes personal data on the workspace owner's behalf. Members may also contact the workspace owner about it. Requests sent to info@grainsift.com are handled and, where needed, coordinated with the workspace owner.

1. Upon account deletion, personally identifying information is destroyed within 30 days. If you are on another user's team workspace, the team's plans, brand and factory masters, decision reports and uploads you worked on are not deleted; they are transferred to the workspace owner. Your entries in that team's activity log remain for up to 400 days, and your usage drawn from the team pool remains in the owner's billing history with your identifier removed. If you own a team workspace, deleting your account closes it: team plans created by members become their own, and team plans you created are deleted.
2. On a team workspace, a member or admin cannot delete their own account or leave the team alone: the request goes to the workspace owner (or an admin, for a member's request), who approves it. If nobody decides within 30 days, GRAINSIFT carries it out. Items a team seat deletes — plans, costing sheets and documents, archive files, order attachments — are first kept in the team trash, where they can be restored, and are deleted for good only when the owner or an admin deletes them or empties the trash. On a personal account these files are deleted right away, and deleted plans stay in your trash until you delete them. Everything you upload while on a team workspace — costing sheets, documents, archive files — is the team's work and stays with the team if you leave or your account is deleted; files you uploaded before joining stay yours.
3. Team activity log entries are deleted automatically 400 days after they are recorded.
4. Price history entries cannot be edited or deleted by users; a correction is added as a new entry. They are kept for as long as the account that owns the plan exists, including after the style is deleted. If a member of someone else's team workspace deletes their account, the entries they wrote on team plans are transferred to the workspace owner together with those plans, and the author name shown on them is kept. Entries on your own (non-team) plans are deleted with your account. Entries written by a factory are kept with the buyer's plan under the same rules.
5. Where retention is required by applicable law, data is stored separately for the required period.
6. Electronic files are permanently deleted in an unrecoverable manner; printed materials are shredded or incinerated.

You may exercise the following rights at any time.

• ✓ Access: review the personal data collected
• ✓ Rectification: correct inaccurate personal data
• ✓ Erasure: request deletion of personal data (account withdrawal). Team data you created in someone else's team workspace is transferred to that workspace's owner rather than erased, and price history entries you wrote on a team plan stay with that plan — see section 4.
• ✓ Restriction: temporarily suspend processing of personal data
• ✓ Portability: export the collected data — Settings → Download all your data gives you one zip (Excel, JSON and your original files). On a team, the workspace’s data is exported by its owner or an admin; each member can export their own account records.

The Service uses essential cookies and browser storage (local storage) to keep you signed in and secure. This includes the time of your last activity, shared across your open tabs, used to sign you out after 30 minutes without activity, and a session identifier that lets us keep one active session per account. If you arrive from a link with a campaign tag or from another website, the browser keeps where you came from (the tag or that site’s name) and sends it once with your account after you sign in, so we can see which channels bring people. We do not use third-party cookies for advertising or behavioral tracking.
