Writesonic — privacy & data policy

Provider: Writesonic. PromptPrivacy score: 85/100. Last verified November 01, 2026.

What happens to your data?

Prompts, queries, and generated outputs are transmitted to underlying model providers (such as OpenAI, Anthropic, or Microsoft Azure) to fulfill requests, under configurations that prohibit foundation model training. Customer data is stored during active service and permanently deleted within 30 days of account closure. Writesonic does not sell personal information for monetary compensation.

Does it train on your data?

Does not train on your content. Writesonic explicitly states that customer inputs, outputs, and usage data—across paid, free, and trial tiers—are not used to train or fine-tune general-purpose, foundation, or large language models by Writesonic or any third-party model provider. De-identified and aggregated data may be used for service improvements, debugging, and AI safety evaluation.

Can you opt out?

Not applicable. Writesonic does not use customer inputs or outputs to train AI foundation models by default, so there is no training mechanism to opt out of.

Data retention

Active account data is retained for the duration of the account. Following account deletion, customer data is kept for up to 30 days before permanent deletion. System access logs and crash reports are stored for 90 days, security audit logs for 1 year, and support tickets for 3 years.

Encryption & security

The policy notes that administrative, technical, and physical safeguards are maintained and highlights that Writesonic is SOC 2 Type 2 audited. Specific encryption ciphers, TLS protocols, and at-rest encryption details are not described in the policy text itself but are referenced via their trust center (writesonic.trust.site).

Is it safe for work?

Yes. Writesonic provides enterprise-ready protections including SOC 2 Type 2 compliance, an official Data Processing Agreement where Writesonic acts as a processor, strict no-training commitments that extend even to free and trial tiers, and configurations that enforce zero data retention or disabled logging with major model providers.
