# Hosting and infrastructure

> Where Campus runs, how data is isolated, and how it is encrypted.

## Where your data lives

Campus runs on its own private database hosted in our own AWS environment. This is not a managed third-party database service: it is network-isolated, not exposed to the public internet, and reachable only from within our environment. No outside provider can reach this database.

## EU data residency

All platform compute and storage run on Amazon Web Services in Frankfurt, Germany (the `eu-central-1` region). This is a single-region setup by design. No workloads, replicas, or backups leave the EU. The one cross-border exception is content sent to the AI coach, covered in [AI and your data](/docs/en/security/ai-and-data).

## Certified infrastructure

The underlying infrastructure is operated by AWS, whose data centers are certified to ISO 27001, SOC 1/2/3, and C5.

<Note>
  We build on certified infrastructure and cite AWS's certifications, not our own. We do not currently hold or claim our own ISO 27001 or SOC 2 certification.

## Encryption

|                |                                               |
| -------------- | --------------------------------------------- |
| **In transit** | TLS 1.2+ (HTTPS) for all traffic              |
| **At rest**    | AES-256, via AWS volume encryption            |
| **Passwords**  | Hashed with bcrypt, never stored in plaintext |

## Backup and resilience

The single-region design is a deliberate residency choice: it keeps platform data in Frankfurt and nowhere else. Backups run hourly, are retained for 7 days, and stay within the same EU region. We target 99.9% availability.
