DPA schedules

Last updated 13 October 2026

These schedules form part of, and should be read with, the Sentivel Data Processing Agreement. Terms defined there have the same meaning here.

Schedule A: Authorised sub-processors

You authorise Sentivel to engage the following sub-processors to process Customer Personal Data in providing the Service. Each is bound by data-protection terms no less protective than the DPA.

Managed Postgres database, authentication and realtime: the primary data store.

Location
European Union (Ireland, eu-west-1)
Transfers
Processed within the EEA: no restricted transfer.

Application hosting and content delivery, with compute pinned to Dublin. Also runs our monitoring probes in Washington, San Francisco, Tokyo and Sydney (see International transfers), and cookieless, aggregate website analytics on our own pages.

Location
Compute in the EEA (Dublin); monitoring probes in the United States, Japan and Australia; vendor is US-based.
Transfers
EU SCCs + UK Addendum.

Transactional and notification email (sign-in links, alerts, status-page subscriber updates).

Location
United States
Transfers
EU SCCs + UK Addendum.

SMS and voice-call delivery for incident alerting.

Location
United States
Transfers
EU SCCs + UK Addendum.

Application error and performance monitoring, including on public status pages. Configured not to collect IP addresses, cookies or request bodies, and to strip tokens from URLs.

Location
United States
Transfers
EU SCCs + UK Addendum.

AI-assisted drafting of incident updates, when you ask for a draft: the incident's status, severity, affected component, monitored host, duration, the updates posted so far and any draft you have started. Also our own automated triage of application errors (error messages and stack traces, via GitHub). Inputs are not used to train its models.

Location
United States
Transfers
EU SCCs + UK Addendum.

Subscription billing and card payments. Card details go directly to Stripe and are never stored by us; we hold a customer reference, plan and invoice history.

Location
United States (with EU processing for European customers).
Transfers
EU SCCs + UK Addendum.

Hosts our source code and the issue tracker our error triage files into: an application error becomes an issue carrying its error message, stack trace and the page path it happened on. Personal data is not deliberately included.

Location
United States
Transfers
EU SCCs + UK Addendum.

Bot protection on the sign-in form (Turnstile), and the off-infrastructure copy of public status pages, which holds only content that is already public.

Location
United States, with global edge processing.
Transfers
EU SCCs + UK Addendum.

Schedule B: Details of processing

Parties. The data exporter is you, the Customer (controller); the data importer is Sentivel Ltd (processor), of 71–75 Shelton Street, Covent Garden, London, WC2H 9JQ, United Kingdom. This schedule also completes Annex I to the Standard Contractual Clauses.

  • Categories of data subjects: your team members and responders; your status-page subscribers (including any you import); visitors to your status pages; people who report an issue through your report link; members of your Slack workspace who use Sentivel's Slack commands or buttons; and anyone whose personal data you include in incident or component text.
  • Categories of personal data: contact details (name, email, optional phone); a reporter's optional email and message; Slack display names attached to actions; visitors' IP addresses, processed transiently and kept only as a keyed hash for rate limiting and password attempts (one day); and any personal data you choose to include in incident or component text.
  • Special-category data: none. Please don’t put special-category data into the Service.
  • Frequency of transfer: continuous, for the duration of your use of the Service.
  • Nature and purpose: hosting, storing and transmitting Customer Personal Data to run monitoring, render status pages and deliver the notifications you configure, plus support (including time-limited, audited staff access to your workspace) and legally-required disclosures.
  • Duration and retention: for the term of your account and until data is returned or deleted as set out in the DPA.

Schedule C: Security measures

The technical and organisational measures Sentivelmaintains (Annex II to the SCCs), appropriate to the risk:

  • encryption in transit (TLS) and encryption at rest for stored secrets;
  • strict tenant isolation so one workspace cannot read another’s data, enforced in the application layer;
  • hashed credentials and API tokens, role-based access control, and optional two-factor authentication;
  • least-privilege access to production, with logging and monitoring;
  • managed, backed-up infrastructure with a hosting region pinned close to the database;
  • a software-development process with code review, and breach detection with an incident-response process.

Schedule D: Standard Contractual Clauses

For restricted transfers of Customer Personal Data protected by the EU GDPR, the EU Standard Contractual Clauses (Commission Implementing Decision (EU) 2021/914) are incorporated and completed as follows:

  • Module Two (controller to processor) applies;
  • in Clause 7, the optional docking clause applies; in Clause 9, Option 2 (general authorisation) applies, with the change notice period set out in the DPA; in Clause 11, the optional redress language does not apply;
  • in Clause 17, the Clauses are governed by the law of Ireland; in Clause 18, the forum is the courts of Ireland;
  • Annex I is completed by Schedule B above; Annex II by Schedule C above; and the Annex I sub-processor list by Schedule A above.

Schedule E: UK International Data Transfer Addendum

For restricted transfers protected by the UK GDPR, the EU SCCs above are incorporated as varied by the UK International Data Transfer Addendum issued by the Information Commissioner under s.119A of the Data Protection Act 2018. The Addendum’s tables are completed with the information in Schedules A–C; the competent authority is the Information Commissioner’s Office; and the governing law and courts are those of England and Wales. If the SCCs or this Addendum conflict with the DPA on a transfer matter, the Clauses prevail to the extent of the conflict.
