The principle
Data protection frameworks around the world share an idea often called data minimisation: collect and keep only what you need for a stated purpose. You'll find it in the EU GDPR (see the European Commission's overview) and in India's Digital Personal Data Protection framework (MeitY). US guidance for businesses makes similar practical points about keeping only what you need. Whatever rules apply to you, it's good engineering: less data in fewer places is easier to secure.

Map the data in each workflow
For each automation, list every field it touches and ask:
| Question | If the answer is no… |
|---|---|
| Does this step need this field to work? | Don't pass it |
| Does the receiving system need to store it? | Pass it for the step, but don't store it |
| Does everyone with access to that system need to see it? | Restrict access or use a different system |
| Do we know when it will be deleted? | Set a retention rule |
Fields to keep out of general automations
- Payment card numbers — use your payment provider's hosted checkout; see PCI standards.
- Passwords, PINs or security answers — never collect these by form or email.
- Government ID numbers, unless a specific, justified process requires them.
- Health, legal or financial details in general inquiry forms — route sensitive cases to a suitable, separately reviewed process.
- Free-text fields copied everywhere — customers type surprising things into "message" boxes.
- Full data exports sent to chat channels or personal email.
Connectors, chat channels and AI tools
- Connector platforms typically store run history, which includes the data that passed through. Check retention settings and who can view history.
- Team chat notifications should carry a summary and a link, not the full record. Chat channels are widely shared and hard to clean up.
- AI tools may store inputs. Check the provider's data use settings, and avoid sending sensitive data unless you've confirmed it's appropriate.
Access and deletion
- Give each person and each integration the least access it needs.
- Record which systems hold copies of customer data, so a deletion request can be completed everywhere.
- Set retention rules for test records, run history and exports.
- When a vendor relationship ends, remove their access and the integrations they set up — see vendor access and offboarding.
Keep your privacy notice true
Whenever you add a workflow that sends data somewhere new, check your website's privacy notice still describes what happens. Privacy and cookie basics for small business websites covers the website side.
Questions
Can I collect extra fields just in case?
Collecting data without a clear purpose increases risk and, in many places, conflicts with data protection principles. Ask for what you need now; you can ask for more later.
Is it safe to send customer data to AI tools?
It depends on the tool's terms, settings and where data is processed. Check whether inputs are stored or used for training, and avoid sending sensitive information unless you've confirmed it's appropriate.
