What does Plain do with personal data?
Respond to customer enquiries and manage support conversations. That is how Privacyboard describes a typical use of Plain, as a starting point you can edit.
The data usually involved: names, Email addresses, Account identifiers, Documents & attachments, Messages & support requests
Is Plain a processor or a controller?
Most customers use Plain as a processor: it handles personal data on their instructions, for the purposes they set. That is the common reading for customer support tools and it is what Privacyboard suggests.
As a processor, it needs a written agreement with you under Article 28, and you should know which subprocessors it uses. Confirm the role against your own agreement, because the way you use a tool can change it.
Where does Plain store personal data?
Plain usually keeps data in United Kingdom (London) for every customer on its standard service, so there is normally nothing to choose. Privacyboard prefills this and you can change it if your setup differs.

How to find yours: Check workspace settings → data and privacy, or the provider’s documentation.
If the data is processed outside the European Economic Area, Articles 44 to 49 require a transfer mechanism, such as standard contractual clauses, an adequacy decision or the EU-US Data Privacy Framework. Your privacy policy should name it.
Which legal basis usually applies to Plain?
For the usual use of Plain, companies most often rely on performance of a contract (GDPR Article 6(1)). The tool is needed to deliver what the person signed up for or asked for.
This is a starting point, not legal advice: the basis belongs to your activity, and you confirm it in your register.
Does Plain have a data processing agreement?
Checked on 5 November 2026. Vendors change their pages, so check the date.
Plain does not publish the full text of its data processing agreement on a public page. The reference page explains how a customer gets or signs it, usually from inside the account. Article 28 of the GDPR still requires a written contract, so get it and keep a copy.
What we noted when we opened the page: Security page stating a DPA is available for companies that need one, linked at plain.com/legal/dpa (not read). Says Plain runs on AWS eu-west-2 (London). Entity and transfer mechanism not stated.
A page that exists does not mean you are covered. Whether the agreement applies to you depends on your plan and on what you accepted, so record the decision yourself in your vendor list.

- 1
In your privacy policy
Name Plain as a recipient, say what it is used for (respond to customer enquiries and manage support conversations) and mention any transfer outside the EEA. Articles 13 and 14 ask you to tell people who receives their data.
- 2
In your vendor list
Add Plain with its purpose, the data involved, its role, its region and a link to the agreement. Privacyboard prefills all of this, you confirm or correct it.

In your processing register
Link Plain to the activities that use it, so each record shows its recipients. Article 30 asks the register to list the categories of recipients.
What to check before relying on Plain
- Set a retention period for closed conversations and attachments.
- Check how you would find and delete one person’s conversations when they ask.
- Review which team members and integrations can read the data.

Questions, answered.
Is Plain GDPR compliant?
Privacyboard does not certify vendors. Compliance depends on how Plain is configured and used, on the agreement you have with it and on your own practices. What can be checked is documented here: it explains how to get a data processing agreement, the usual role and the data location. Read the agreement itself before relying on it.
Does Plain have a DPA?
Plain does not publish the full text of its data processing agreement on a public page. The reference page explains how a customer gets or signs it, usually from inside the account. Article 28 of the GDPR still requires a written contract, so get it and keep a copy. The reference page is https://www.plain.com/docs/product/security.
Is Plain a data processor?
Usually, yes. Most customers use Plain as a processor that acts on their instructions. Check your own agreement and how you use the tool, because the role can differ.
Which legal basis applies when I use Plain?
For the usual use of Plain, companies most often rely on performance of a contract (GDPR Article 6(1)). The tool is needed to deliver what the person signed up for or asked for. This is a starting point, not legal advice: the basis belongs to your activity, and you confirm it in your register.

Do I need to mention Plain in my privacy policy?
Yes, if Plain handles personal data for you. The GDPR asks you to tell people who receives their data (Articles 13 and 14). Name the vendor or its category, say what it is used for and mention any transfer outside the EEA.
How do I add Plain to my vendor list?
In Privacyboard, pick Plain from the catalog. The purpose, the data, the suggested role and a link to its agreement are prefilled, and you confirm each one. Creating a workspace is free.
