No one would deny that the most important feature of an NSFW AI chat is not the conversation itself, but personal data privacy and security.

An article from The Atlantic in October 2024 sharply pointed out: "Your chatbot transcripts may be a gold mine for AI companies," explaining that OpenAI, the world's leading AI company, collects large amounts of user chat logs for its ChatGPT product, compiling them into the WildChat dataset with over a million entries. Researchers then analyze the dataset to study interaction information and push ads.

When we open the many free AI chat apps on our phones, which companies can we trust to truly take the user's perspective into account and handle data collection, storage, encryption, and deletion securely? And which companies don't care about these aspects, viewing user data as an asset ready to be sold?

We will review the privacy policies of several popular 2025 NSFW AI chat products, summarizing their security features based on the following three aspects (with a 5-star rating), to select the product with the highest privacy security.

The areas we focus on are:

1. Data Storage and Encryption

   Specific focus: How is the chat content encrypted? Can team members view user chat content?

2. Data Collection and Usage

   Specific focus: How will the collected data be used?

   (Note: We found that the following apps collect user-provided information, which is used for feature improvements, personalized experiences, and potentially for advertising or third-party sharing. This will not be repeated below.)

3. Privacy Information and Data Deletion

   Specific focus: Can users permanently delete all their chat records and account information with a single click?

Although these popular 2025 NSFW AI chats clearly outline their privacy policies, a detailed analysis reveals that apps like CrushOn (Security Rating: 2.5 stars), JanitorAI (Security Rating: 2.5 stars), EVA AI (Security Rating: 3 stars), and Hi, Waifu (Security Rating: 3 stars) still pose significant security risks regarding user data encryption, the scope of data collection, and permanent account deletion. Furthermore, all these products potentially or already use user data for internal analysis and third-party advertising purposes.

Among these apps, Tipsy Chat (Security Rating: 4 stars), Talkie (Security Rating: 3.5 stars), and Replica (Security Rating: 3.5 stars) stand out in terms of encrypted data transmission and storage, the absence of current usage for advertising purposes, and the ability to permanently delete all privacy-related information with a single click.

We recommend that before using any free NSFW AI chat, users should thoroughly understand the following three basic aspects: data storage and encryption, data collection and usage, and deletion methods. It's also important to be clear about the legal rights applicable to users in different regions before logging in and creating any accounts to start chatting.
