Verdict
On paper, Nastia covers the basics of an adult companion app: uncensored chat, a detailed character creator, group chats, voice messages, 4K selfies and short video clips, all in the browser, with a free tier that needs no card. The catches are in the details. Official pages list Standard at $11.99 and Unlimited at $15.99 a month, but they disagree with each other and with third-party sites on prices and limits. Refunds are ruled out, and the most common Trustpilot complaints are unexpected charges and memories that reset. The operator, a French SAS, is named and the privacy policy is current, but the policy does not say plainly whether chats are used to train its models.

- No refunds unless the law requires one or a technical error occurred
- Trustpilot users report unexpected charges, including a monthly plan billed as yearly
- Users report memory resets and replies that go off-topic
- No official store apps, and lookalike 'Nastia AI' listings come from other developers

NastiaAverage of all 77 apps
Overview
Nastia is run by Nastia Cybernetics, a French SAS registered in November 2023 in Saint-Laurent-du-Maroni, French Guiana, and it launched in 2023. It is a Progressive Web App that runs in any modern browser and can be installed on iOS (through Safari), Android, Windows and macOS. There is no official App Store or Google Play app, and several 'Nastia AI' store listings belong to other developers. You can chat one-on-one or in group chats where up to 10 companions talk to each other. You can build your own character or pick one of 98 preset adult anime characters, and the site says chats are never shown to other users.
Media includes voice messages, an image generator with pose and face references, negative prompts and upscaling, and short videos made from a text prompt or by animating a generated image. The Unlimited plan advertises 4K selfies, 1080p video and custom voice cloning. Third-party listings and an older official comparison mention voice calls, but the current plan cards do not. Free users get one companion and a daily token allowance. Tokens pay for images and voice rather than chat text, but the official site publishes no token amounts. The site promises persistent memory across sessions, though users report resets, and it does not name the AI model behind the chat.

Privacy & safety
Nastia is run by a named French company, has a current privacy policy and no known breaches. However, it shares data with advertising and analytics providers, keeps flagged chats for up to 7 years and does not say plainly whether chats train its models.
- CautionThe September 2026 privacy policy does not say plainly whether chats train AI models, and it offers no opt-out. It cites a legitimate interest in improving companion replies. The data it collects includes chats, memories, voice samples, generated media, your IP address and your approximate location.
- CautionData is shared with providers for hosting, AI, payments, analytics and advertising. It is processed outside the EEA, including in the US, where the service is hosted. Reports and rule-violation records, including the related chats, are kept for up to 7 years.
- NoteThe operator, Nastia Cybernetics, is a named French company, EU users are pointed to the CNIL, and the policy says data is not sold. The policy gives an email contact but no street address.
- NoteYou can delete chats and media at any time, but you cannot delete the account while a subscription is active. No breaches, lawsuits or regulator actions found.
What users say
Independent feedback is thin. Trustpilot rates Nastia 2.1 from 18 reviews (October 2026), and 72% of them are one-star. Billing is the most common complaint, including unexpected charges and a monthly plan billed as yearly. Reviewers also report memory resets and failed image or video generation. Positive reviews praise lifelike conversation and help with loneliness. SmartCustomer has a single 2-star review, and there are no official store apps to rate.
Nastia FAQ
Is Nastia free?
Yes. The free plan is 'free forever' with no credit card. It includes uncensored chat, basic customization, one companion and a daily token allowance. Tokens are spent on images and voice rather than chat text. The official site gives no token amounts; Plisio (June 2026) reports about 290 a day, and Stork.ai says voice messages, image generation and advanced memory are not included for free users.
How much does Nastia cost?
The official plan cards (October 2026) show Free at $0 and Unlimited at $15.99 a month. An official comparison page adds a Standard plan at $11.99 a month. The official cards show no yearly price, and the in-app membership page needs a login.
Does Nastia allow adult content?
Yes. Nastia is for adults 18+ and allows fictional sexual content between adults. It bans anything that depicts or suggests minors, including childlike or 'aged-up' characters, as well as real identifiable people, non-consent, incest, bestiality, extreme violence and trafficking. Everyone confirms they are 18+ on arrival. In countries whose law requires more, an independent provider runs a facial age estimate, a card check or an ID check, and Nastia says it receives only the result, the date and the country. Elsewhere the check is a one-tap confirmation, which Plisio calls weak.
Is Nastia safe and private?
Nastia is run by a named French company, has a current privacy policy and no known breaches. However, it shares data with advertising and analytics providers, keeps flagged chats for up to 7 years and does not say plainly whether chats train its models.
