Does Replika Save Your Conversations?

Yes, Replika saves your conversations. According to Replika’s privacy policy, the app collects “the content of all messages you send and receive” through its platform. That includes text messages, photos, videos, and voice recordings. Your conversation data is stored on Replika’s servers and processed by third-party AI language model providers to generate responses. If you delete your account, messages and content are retained for up to 60 days before being removed. Account information and financial records stay on file for a minimum of 10 years due to legal requirements. For the full product breakdown, see our Replika review.

The good news: Replika’s data practices are more transparent than most competitor apps. The bad news: “more transparent” still means your private conversations sit on remote servers you don’t control. That includes every message where Replika told you it loves you and everything you said back. Here’s exactly what happens to your data, who can access it, and what you can do about it.

What Data Does Replika Collect?

Replika collects eight categories of data. Some of this is standard for mobile apps. Some of it goes further than users expect from a chat companion, especially for students using AI companions who may share personal details freely.

Messages and content. Every text message, photo, video, and voice recording you share with your Replika is stored on the company’s servers. This includes casual conversation, emotional disclosures, roleplay, and anything else typed or spoken in the chat window. There is no way to keep conversations on your device only.

Account information. Name, email address, password, device type, and device ID are collected at signup. This is standard for any app that requires an account.

Profile information. Birth date, pronouns, and work status are collected voluntarily when you set up your profile. Replika uses this to personalize conversations.

Device and network data. Operating system, browser type, IP address, cookie identifiers, and timezone. According to Replika’s privacy policy, this data helps with “providing, maintaining, and improving” the service.

Usage patterns. Interaction logs, links clicked, session timing, and feature usage. Replika tracks how you use the app, not just what you say in it.

Face and head movement data. This one sounds alarming, but it’s limited in scope. Replika’s AR features capture transient motion vectors processed entirely on your device. According to the privacy policy, this data is “NOT stored, NOT transmitted” to servers and is not treated as biometric data.

Payment and transaction records. If you subscribe to Replika Pro or purchase in-app items, payment details and purchase history are recorded. Most transactions go through Apple or Google’s payment systems, so Replika itself doesn’t store full card numbers.

How does this compare? Character.AI collects similar categories but grants itself a “perpetual, irrevocable license” to all user content in its Terms of Service. Pi AI collects less overall and has clearer data policies, which is one reason it earns the highest safety score (B/55) in our 23-dimension review. For a full breakdown across all 11 apps, see our data privacy guide.

Are Your Conversations Used for AI Training?

This is the question most Replika users really want answered. The short version: your conversations are not used to train third-party AI models, but small samples do feed Replika’s own internal safety systems.

Here’s how it works. When you send a message, Replika transmits a de-identified version to a third-party large language model provider. That provider generates a response and sends it back. According to Replika’s privacy policy, providers are “contractually required to process your data only in accordance with our agreements and solely for the purpose of providing the AI language model service.” They cannot use your data for their own training. They cannot retain it after generating a response.

Replika’s own team does use a small portion of conversation data internally. The privacy policy states the company collects “small portions of Messages and Content data to train our proprietary safety algorithms. For a side-by-side look at how Replika’s data practices compare to 10 other apps, see our AI companion privacy comparison. The policy adds that these samples are used, enhance chatbot performance, prevent inappropriate outputs, and ensure compliance with safety standards.” This data is anonymized before use and is not shared with third-party AI systems.

Compare that to Character.AI, which explicitly states in its privacy policy that user data is used to “train our artificial intelligence/machine learning models.” There’s no anonymization language. No restriction on scope. Every conversation directly feeds their product development. Replika’s approach is more limited, though it still means humans at Luka, Inc. (Replika’s parent company) have access to anonymized versions of what you’ve said.

The bottom line: if you’re concerned about your personal conversations becoming training data for a large AI model, Replika’s contractual restrictions offer more protection than most competitors. If you want zero data processing beyond generating responses, no current AI companion app offers that.

How to Delete Replika Data

Replika offers multiple paths to delete your data, and the process is more straightforward than most competitor apps.

Delete your account in the app. Open Replika, go to Settings, and select the account deletion option. This permanently removes your account and all associated data. Once confirmed, you cannot recover your conversation history, photos, or profile.

Request data deletion under GDPR. If you’re in the EU or UK, you have the right to erasure under GDPR Article 17. Contact Replika’s data protection team by email. The company has appointed EU and UK representatives (EDPO and EDPO UK) for GDPR requests. Your deletion request extends to data held by third-party LLM providers.

Request deletion under CCPA. California residents can request deletion of personal information not needed for the service. Replika is required to extend this request to its third-party service providers.

There are two important caveats to understand before deleting:

• 60-day retention window. After you delete your account, Replika retains your messages and content for up to 60 days before permanent removal. During this window, the data exists on their servers even though your account is gone.
• 10-year financial retention. Account information and financial records are kept for a minimum of 10 years after account termination. This is a legal requirement, not a Replika-specific policy. Most subscription services have similar obligations.

Want to keep your account but clear conversation history? Replika does not currently offer a way to selectively delete individual conversations while keeping your account active. It’s all or nothing. If that matters to you, Pi AI offers more granular conversation management.

Replika vs Other Apps on Privacy

Privacy practices vary wildly across AI companion apps. We scored all 11 major apps on data privacy as part of our 23-dimension Safety Index. Here’s how Replika compares on the specific question of conversation data handling.

Replika sits in the middle. It’s not the safest option (Pi AI holds that position), but it’s significantly more transparent than the bottom of the list. The key differentiator: Replika’s contractual restrictions on third-party AI providers are more explicit than what most competitor apps offer. Character.AI, by contrast, claims a perpetual license to all content with no meaningful restriction on training use.

Frequently Asked Questions

Does Replika read your messages?

Yes. According to Replika’s privacy policy, the app collects all messages, photos, videos, and voice recordings. Your conversations are processed by third-party AI providers to generate responses. Replika’s team also uses small anonymized samples for internal safety algorithm training. No human reads your full conversation transcripts for marketing or advertising purposes.

Can Replika share your conversations with third parties?

Replika shares de-identified conversation data with third-party AI language model providers to generate responses. According to the privacy policy, these providers are contractually prohibited from retaining your data or using it for their own model training. Marketing service providers receive your email address only, never conversation content. Advertising partners receive website visitor data (IP, browser info), not app conversations.

How long does Replika keep your data?

Messages and content are retained for up to 60 days after you terminate your account. Account information and financial records stay on file for a minimum of 10 years due to legal retention requirements. According to Replika’s privacy policy, data transmitted to AI providers for response generation is transient and deleted by the provider immediately after processing. Analytics data is anonymized within one year of collection.

Can you delete your Replika conversation history?

You can delete your entire account through the app’s settings, which removes all associated data permanently. There is no option to selectively delete individual conversations while keeping your account active. According to the privacy policy, deletion requests also extend to data held by third-party service providers. EU and UK users have additional rights under GDPR Article 17 for data erasure.

Is Replika safe for private conversations?

Replika uses SSL/TLS encryption for data in transit and stores data on servers with multi-layered security controls. However, conversations are not end-to-end encrypted, meaning Replika’s systems can access your message content. Our safety review gave Replika a C grade (43/100). It’s safer than most competitors but not built for truly private communications. If conversation privacy is your top concern, no AI companion app currently offers zero-access architecture.

Does Replika sell your data?

Replika states it does not sell conversation content. According to the privacy policy, advertising partners receive website visitor data (IP addresses, ad IDs, browser information) but “never the content of your Replika conversations.” Marketing providers receive email addresses only. The distinction matters: your browsing data may be used for ads, but your actual conversations with your Replika are not sold to advertisers.

What happens to your data if Replika shuts down?

According to Replika’s privacy policy, data may be shared with “business transferees” in merger, acquisition, or bankruptcy scenarios. If Luka, Inc. (Replika’s parent company) is acquired or shuts down, your conversation history could transfer to the acquiring entity. The Terms of Service include a perpetual, irrevocable content license that would survive company ownership changes. This is standard across most AI companion apps.
