Trust and security
Security you can check.
Here you find where your data lives, who sees it, how we use AI and what the “With Locins” sticker stands for.

Built like large data platforms.
Data in layers: raw data stays unchanged, every answer can be traced back.
One catalogue for permissions: who may see what is kept in one place.
Origin of every number: every number shows which system it comes from.
Sharing via an open standard: live, without copies, with expiry and revocation.
Technical
unchanged raw copy per source with timestamps, origin per field, a central permission catalogue with grants as records, sharing via OpenSharing, an audit log per access. The Locins OS page explains the layers in detail.
Your data stays in the EU.
Locins runs in data centres in the EU. On request there is a dedicated instance in Germany or Switzerland.
Every business has its own data space. No business sees another's data.
Encrypted in transit and at rest. Backups run automatically.
Where a service works outside the EU, for example for sign-in, it is in the list of subprocessors.
Technical
Microsoft Azure, EU region. Tenants separated by row-level security per Terminal. TLS in transit, database encryption at rest, automatic backups with point-in-time restore.
AI with fixed rules.
- 1
The major models run in the EU. Their providers do not learn from your data.
- 2
Connect in Locins AI learns only with consent and without names. Build never learns from the data of businesses or guests.
- 3
AI answers only from released data, with a source, and is recognisable as AI.
- 4
Booking and paying only with confirmation by a person. Every AI answer is in the log.
- 5
If you connect your own AI, such as ChatGPT or Claude, it only sees what you release, and you can end the connection at any time. Your AI provider's rules also apply to that connection.
Technical
training contractually excluded for the models via Azure, tool permissions per building block, protection against injected instructions in guest messages, a log entry per call with model, version, source and grant.
You control who sees what.
Team: roles for owners, admins and staff, per project.
Guests: they see in their Locins Pass who sees what about them, and take back a grant with one tap.
Partners and regions: they only get what you release, aggregated, with purpose and expiry.
Log: every access is in the audit log: who, what, when and why.

Is there Locins here?
The “With Locins” sticker is on the door of places that work with Locins.
- 1
Free: every place we work with gets the sticker and support.
- 2
QR code: it leads to the Locins Tag of the place, where you see offers and book directly.
- 3
Real: account, legal notice and contact person are checked.
- 4
Real guests: only people who were really there can leave a review.
- 5
Fair: prices as shown, clear cancellation rules.
Anyone who breaks the rules loses the sticker.
The sticker is a Locins mark, not a certificate from a testing body.
