Data protection
Your data stays yours
Where your data lives, who touches it, and how to see, take or delete it, on one page in plain words.
At a glance
What we promise
Stored in the EU
Accounts, messages and files are kept in Frankfurt, Germany.
Encrypted
Everything is encrypted in transit, and messages, notes and keys are encrypted in our database too.
Never sold, never used for training
We don't sell personal data or use your conversations to train AI models, ours or anyone else's.
No tracking cookies
Only the cookies Seler needs to work, and cookieless analytics, so there's no banner to click. The website chat follows a visitor's pages only once they open it or agree.
Our team needs your OK
Support can enter your workspace only when the owner approves, for a set time, and every visit is recorded.
Your rights, in the app
Download your data, edit your details, turn off marketing and delete your account yourself, or ask us for anything else.
Who is responsible
Two kinds of data, two roles
Your account
We are the controller
For your details as a Seler user (your account, your workspace's plan and your visits to our website), we decide how the data is used, and the privacy policy explains it.
Your customers' messages
You are the controller, we are your processor
The messages and records of a business's customers belong to that business. We process them only to run Seler for it and only on its instructions, under our Data Processing Addendum.
Your rights
See it, fix it, take it, delete it
Under the UK GDPR, and the EU GDPR where it applies, you can access, correct, erase, restrict and move your data, object to how we use it, and withdraw consent at any time.

- 2
We confirm it's you
We may ask one or two questions so that nobody else can get your data.
- 3
We answer within a month
Free of charge. If a request is complex, we'll tell you why we need longer.
Are you a customer of a business that uses Seler? Contact that business first: it decides about your data. If you write to us, we'll pass your request on.
You can also complain to the UK Information Commissioner's Office (ico.org.uk) or the data protection authority where you live.

When data leaves the UK or the EU, we rely on an adequacy decision or the UK–US Data Bridge where they apply, or on the EU Standard Contractual Clauses with the UK International Data Transfer Addendum.
For businesses
A Data Processing Addendum, built in
Our Data Processing Addendum is part of our terms, so it applies the moment you use Seler, with no paperwork. It covers what GDPR Article 28 asks for:
Read the addendum- We act only on your instructions
- Confidentiality and security measures
- Sub-processors, with 30 days' notice and a right to object
- Help with requests, assessments and regulators
- Breach notice without undue delay
- Deletion or return when you leave, and audits
You're the controller of your customers' data, so tell them how you use it, including about the Seler chat on your website. When a customer asks, an owner or manager can download a copy of their data, or erase them, from their page in Seler.
Security
How we protect it
- HTTPS/TLS for everything sent to and from Seler
- AES-256-GCM encryption for messages, notes, customer fields, sheets and channel keys
- Private files that open only through links that expire
- Two-step sign-in and a list of signed-in devices
- Approved, time-limited and recorded support access
- Notifications that can hide message text, set by each person
- Message content stripped from error reports
- Breach notice to the ICO within 72 hours where the law requires it
