Security Overview

Last updated: 5 October 2026

How Sigbot protects the data that moves through connected inboxes — from authentication and encryption to how we respond when something goes wrong.

1. Infrastructure

Sigbot is built on established cloud infrastructure rather than self-managed servers, so the Services inherit the physical and network security controls of our providers:

Hosting

Google Cloud Platform, EU: data in Firestore eur3, processing in europe-west2 (London)

Application backend

Firebase (Google)

Payments

Paddle (merchant of record)

2. Encryption

3. Authentication and Access

Your account

Mailboxes and internal access

4. Monitoring and Logging

We log access to production systems and monitor for anomalous activity. Application logs are kept for 30 days; a separate security log of refused sign-ins and requests, failed mailbox connections, and staff and administrative actions is kept for 400 days, as are admin-activity logs (see section 9); these periods are reviewed in line with our data minimisation obligations.

Sigbot's code redacts email addresses before writing them to application logs. Where one of Sigbot's own log entries refers to an address, whether one of your contacts' or your own, it keeps only the first character and the domain (for example, a…@example.com). The sign-in service (Google Identity Platform) keeps its own log of each sign-in, sign-up and account change, with the full email address used, the IP address, browser details and the outcome, for 30 days; failed attempts are also kept for 400 days in the security log.

5. Vulnerability Management

We welcome reports of potential security issues in sigbot.app, sigbot.co, our backend and our mobile apps through our Vulnerability Disclosure Policy. No independent penetration test has been carried out yet. We intend to commission one, and will publish its date and a summary here once it has been done.

6. Incident Response

We maintain a written incident response plan for identifying, containing, and notifying customers of security incidents affecting their data. Under our Data Processing Addendum, we notify affected customers of a personal data breach without undue delay and in any case within 72 hours of becoming aware of it.

7. Subprocessors

A current list of subprocessors that may process Customer Data is maintained in our Data Processing Addendum, and its Annex D sets out our technical and organisational measures. The Subprocessors page sets out the same list in one table — purpose, data, location and transfer mechanism for each — and lets you ask to be emailed each change. We give at least 14 days' notice before adding or replacing a subprocessor.

8. Compliance Status

Sigbot is a growing company and is transparent about where formal certifications currently stand:

Our certification status, our answers to the Cloud Security Alliance security questionnaire (CAIQ) and every security document are collected in the Trust Centre.

9. Data retention

Retention is automatic. The periods below are enforced by scheduled deletion and time-to-live policies on our database; nothing on this list needs a request from you.

Everything above, when you delete your account—Your subscription is cancelled first, then all of it is erased at once, except the logs, which age out on the schedule above. Copies in backups age out within 14 days.

Billing records are kept for as long as tax and accounting law require; see Delete your account.
