- Retention Default
- Writer describes a zero data retention approach — data is stored only as long as needed to build on the platform — and organisation-wide data controls include an automated deletion schedule.
- Retention Exceptions
- Writer's own models are trained on publicly available and licensed data, which may include personal information; the commitment is that no customer input or output is used, not that no personal data was used to build the models.

- Eu Procurement Reason
- One of the few SaaS-embedded vendors that builds its own models rather than reselling OpenAI or Anthropic, which removes a whole layer of supply chain — and it publishes a subprocessor table with EU processing locations for the main infrastructure providers. Certified to the EU-US DPF with SCCs as backup, and unambiguous that customer inputs and outputs are never used for training. It remains a US processor and the EU location is per-subprocessor rather than an EU-only product tier.
