| #2 Enterprise-backed chat | Pi AI | Strong policy infrastructure (AI Companion Guides) | |
| #3 GDPR-style mainstream | Replika | Formal deletion; 60-day retention window (CompanionWise) | |

- Deletion quality varies wildly — Nomi cited cleanest; Character.AI perpetual licenses cited (CompanionWise).
- NSFW platforms often have weaker documented deletion — read policies before explicit content (AI Companion Guides).
- AISoul fits adult users who want private companion chat, discreet one-time payments, and no subscription zombie renewals.
- Use our adult AI chat privacy checklist before any platform.
What “privacy” should mean for companion apps
| Dimension | Question to ask |
|---|---|
| Deletion | Does account delete actually erase messages? |
| Retention | 60 days? Forever “license”? Training archives? |
| Export | Can you download your data? |
| Billing | Discreet descriptor on card statement? |
| Encryption | TLS in transit — rarely true E2E |
| Adult content | Extra risk if policies are vague |
Quick comparison
| Platform | Deletion (cited) | Post-delete retention | Safety score (CompanionWise) | Adult / NSFW |

| Replika | GDPR path; ~60 days | Content license survives | C/38 | SFW for new users |
| Character.AI | Buried settings | Perpetual license cited | F/22 | Romance restricted |
| AISoul | Account controls; verify in-app | Adults-only private thread | — | 18+ core |

Best deletion transparency: Nomi AI
Nomi AI is cited for permanent account deletion removing Nomis and messages (CompanionWise). Trade-off: conversation data powers Mind Map memory — you are trusting Nomi with intimate context (nenawow.com cited in prior research).
Choose Nomi if: memory + deletion transparency matter more than images.
Not for: unlimited in-chat photos — text/memory-first.
Best mainstream policy: Replika
Replika offers GDPR Article 17 paths; messages retained up to ~60 days after closure (CompanionWise). Beats Character.AI on documented timelines.
Limitation: Not an adult visual privacy pick — NSFW removed for new accounts.
Best for adult private chat + billing control: AISoul
**AISoul is adults-only with a private 1-on-1 companion thread** — not a public character feed.
Privacy-relevant product choices:
- No auto-renewal — one-time plans ($4.99 7-Day Pass through $49.99 Annual) reduce “forgotten subscription” leaks on statements
- Fictional companions — designed for AI-generated intimacy, not real-person impersonation
- Beginner-friendly — fewer third-party API keys than Janitor/BYOM setups
You still must: avoid sharing real PII you would regret; read Privacy Policy and adult privacy checklist.

Platforms to approach carefully
AI Companion Guides flags several NSFW platforms with alarming or unclear deletion — including some RP browsers. CompanionWise rates Character.AI F/22 for safety/privacy dimensions.
Rule: If you cannot find account deletion in settings + policy, treat chat as semi-public.
Practical privacy checklist (any app)
1. Read Privacy + Terms — search “retain,” “train,” “license”
2. Use a dedicated email — not work/school
3. Avoid real names, addresses, employer info in flirt logs
4. Cancel subs immediately after purchase if you fear auto-renew (AI Companion Pricing Guide tip)
5. Export data if offered — then delete account
6. EU/UK users — invoke GDPR erasure if in-app delete is incomplete
