Is Nastia AI safe?

Nastia is an 18+ service, and that much is verified from its terms. What we could verify stops there: its privacy notice is from January 28, 2023, it collects names, email, phone, passwords, card data, and sensitive data such as sexual orientation, and the homepage’s promise of 100% private conversations is contradicted in part by the notice’s own sharing language. Chat retention and training treatment could not be verified from the policies we could reach (checked 2026-08-10).

What the policy says

Nastia’s privacy notice is a generic, template-style document last updated January 28, 2023. It describes collecting names, email addresses, phone numbers, usernames, passwords, billing addresses, and debit or credit card numbers, with payment data stored by Stripe. It also names sensitive categories it may process with consent, including data about a person’s sex life or sexual orientation.

On sharing, the notice says information may be shared with service providers and in business transfers, and it states that no sale of personal information occurred in the preceding twelve months. The homepage says conversations are “100% private” and that Nastia “never share[s] or sell[s] your information to third parties.” The notice’s provider and business-transfer language is a more careful statement than the homepage’s headline, and both pages should be read together.

The notice also lists purposes beyond chatting: marketing communications, targeted advertising, usage analysis, and fraud prevention sit alongside account management and service delivery. The terms add two structural facts: the services are hosted in the United States, and using Nastia from other regions means consenting to transfer of your data to the US. Governing law and dispute resolution are set in the same document.

Age rules

The terms, last updated May 3, 2024, say the services are intended for users at least 18 and that persons under 18 are not permitted to use or register. The privacy notice says the same. The homepage positions the service for adults. How age is verified at signup could not be verified from the pages we could reach (checked 2026-08-10).

Deletion and export

The notice says personal information is kept no longer than the period in which a user has an account, and that account termination deactivates or deletes information from active databases, with fraud-prevention, troubleshooting, legal, and backup exceptions. The site’s FAQ describes deletion through Settings. What deletion means for chat history, generated images, and copies held by providers could not be verified from the policies we could reach (checked 2026-08-10). Access, rectification, erasure, and portability rights are described for EEA, UK, and Canada users.

Those rights are stated in the notice; the practical deletion flow for chat history and generated content is not described anywhere we could reach, so a deletion request is the way to test the promise. Ask what happens to each record type before you submit one, and keep the request confirmation.

Moderation and human review

No moderation or human-review language appears in the privacy notice, terms, or homepage sections we could reach. The site links content-removal and 18 U.S.C. 2257 compliance pages in its footer, but their contents were not part of this review. Whether messages are reviewed by people is therefore unverified (checked 2026-08-10).

What to check before subscribing

Before you pay for a Nastia plan:

1. Ask support directly what the chat retention period is and whether conversations train or feed any model; the current policies do not say.
2. Note the notice’s age: January 28, 2023. A three-year-old privacy notice leaves a lot unstated about how the service works today.
3. Read the homepage privacy claims against the notice’s sharing language before assuming “100% private” covers providers and support staff.
4. Check the subscription terms, including auto-renewal, cancellation, and the non-refundable purchase language in the terms.
5. Consider what the uncensored positioning means for moderation: if nothing is filtered on the way in, ask what protects your messages on the way out, because the policies we could reach do not describe provider handling or retention for chat content.

How Riho compares

Riho is an 18+ relationship-first AI girlfriend app with current, readable privacy material. The Riho privacy page explains what Riho stores, how you can review, correct, export, or delete memories, and the settings for contact, location, and messages. Riho identifies the partner as AI and states the age requirement at the point of use.

Where Nastia’s evidence is thin and dated, Riho documents its data handling on one page and separates stored relationship data from inference-provider handling of prompts.

The comparison is not only about features. Nastia’s evidence base is a 2023 notice and a 2024 terms page, with an uncensored positioning that leaves provider and retention questions unanswered. Riho’s evidence base is a current privacy page that names what is stored, what is routed to inference providers, and what you can correct or delete. When the documents differ this much in age and specificity, the safer starting point is the service that can answer the checklist.

The safety checklist lists the questions to ask both services; the difference is how many of them each service can answer today.

Frequently asked questions

Is Nastia AI legit?

It is an operating service with published terms, a privacy notice, and a paid membership model. “Operating” and “documented enough to judge” are different; its core privacy notice is from 2023 and does not answer chat retention or training questions.

Is Nastia AI free?

The site describes a free tier with daily messages and paid plans for unlimited messages, voice, and image generation. Exact current pricing was not part of this review.

Does Nastia store my conversations?

The privacy notice does not clearly describe chat-content retention, and the terms’ contribution license gives Nastia broad rights over content you contribute. The practical answer could not be verified from the policies we could reach (checked 2026-08-10).

Can I cancel my Nastia subscription?

The terms say purchases are non-refundable and subscriptions can be cancelled from the account, with access continuing to the end of the paid term.
