Short answer
Here are the facts. The company behind Walter Writes is Walter AI Inc. in Montréal, Canada, with services hosted in the United States. Its privacy policy says text is processed by its own self-hosted AI models, card details are held by a third-party payment processor, and you can request deletion. Academically, safety depends on the rules of your institution.
"Is Walter Writes safe?" means two different things depending on who asks. Some people want to know whether their text, account and card are safe. Students usually want to know whether using it is safe for their grades. This page answers both with what Walter's own privacy policy and terms of service say, read in November 2026, so you can judge for yourself.
For the rest of the product, see the Walter Writes guide.
Is Walter Writes SOC 2 Type II compliant?
Yes. Walter Writes holds a SOC 2 Type II report, available on request through its trust centre. A SOC 2 Type II report is an independent auditor's attestation that a company's security controls were in place and working over a period of months, not just on one day. Of the dedicated humanisers we checked in November 2026 (Undetectable AI, Grubby AI, Phrasly, WriteHuman, StealthWriter, StealthGPT, Ryne and HIX), none publishes a SOC 2 Type II report on its site. Humbot says it follows "ISO 27001 and SOC 2 frameworks" without naming a report type. Grammarly, a writing suite with a humaniser feature, does hold SOC 2 Type 2. That makes Walter the only dedicated AI humaniser in our checks with a SOC 2 Type II report.

Its privacy policy refers to Walter Writes AI Inc. and its affiliates. Support is reachable at support@walterwrites.ai, through in-app chat and through a public help centre.
What happens to the text you paste in?
| Question | What Walter publishes |
|---|---|
| Who processes my text? | Walter says it processes text using its own self-hosted AI models |
| Is text from Google Docs shared? | Google Docs text is sent only to Walter models for the humanising you request, not to third-party AI providers, and is not used for advertising or sold |
| How long is data kept? | As long as necessary to provide the service and meet legal obligations, with periodic backups |
| Can I delete my data? | Yes: request deletion through Walter support or the privacy request form; account deletion is permanent |

Two points worth knowing before you paste anything sensitive. First, the privacy policy says Walter cannot guarantee absolute security, like every service. Second, it uses analytics and advertising cookies, including Google Analytics with IP anonymisation, and works with advertising partners. If a document is confidential, check your employer's or university's rules on online tools first.
Is it safe to pay Walter Writes?
Walter's terms list Visa, Mastercard, American Express and Discover. Its privacy policy says financial details are sent to and stored by a third-party payment processor, not by Walter. The real money risks are policy ones, all published:
- Auto-renewal: every plan renews until you cancel, and renewals are final and non-refundable.
- Narrow refunds: only first-time subscribers within 3 days who have used 1,500 words or fewer.
- Annual plans are charged as one yearly payment.
- Chargebacks: the terms say a chargeback can lead to immediate, permanent account termination. Contact support first.
Our cancel and refund guide covers how to stay on the right side of each rule.
Is Walter Writes safe for school and university work?
That is a question about your institution's rules, not about the software. Walter's own privacy policy includes an academic integrity policy: it says Walter does not condone academic dishonesty, users agree not to use it to cheat, accounts that do can be terminated, and Walter is not responsible for consequences such as misconduct findings. Many universities allow AI for planning or editing with disclosure and ban it for assessed writing.
On detection, Turnitin announced detection of humaniser-modified text in August 2025, and no tool can guarantee a score. Our page on Walter Writes and Turnitin covers the evidence. Detectors also misfire: the Stanford HAI study found non-native English writing was wrongly flagged far more often, which is why many people rewrite their own text.
Is the Walter Writes app or extension safe?
Install the app only from the App Store or Google Play and the extension only from the Chrome Web Store. Third-party APKs and "mod" versions are not official; see our Walter Writes app page. Walter's extension page says text is sent for processing only when you invoke a Walter tool from the extension.
A five-point safety checklist
- Read the refund and renewal rules before paying.
- Choose monthly billing if you only need one month.
- Do not paste confidential or personal data you are not allowed to share.
- Download apps only from official stores.
- Check your institution's AI policy before using it on assessed work.
