The Most Private AI Companion Apps in 2026, Ranked

Five checkable criteria, one score out of five, fifteen apps I’ve actually run on my own accounts. No paranoia, no vibes, and no grade I can’t defend line by line.

People asking for the most private AI companion almost never want a lecture about encryption. They want a name. So here’s the ranking I wish somebody had handed me in early 2025, when I signed up for my first companion app with my real email address like an idiot, and again this August when I finally read what one of those companies had been keeping.

Quick orientation, because I’ve written about this from three other angles and they’re all different jobs. If you want the background on what these companies collect and why, read the full privacy guide. If you want a method for vetting an app nobody has reviewed yet, the privacy checklist is the one to bookmark. This page is narrower and blunter. It answers one question: which app should you pick if privacy is the thing you’re optimizing for.

Nothing here is sponsored. Every app on the board came off my own card or my own hard drive, and two of them I’m still paying for.

The one-paragraph answer

If you want the name and nothing else

Hammer AI wins, 4.7 out of 5. Run its local models on your own machine and there's no account, no email, no server, and no transcript existing anywhere except your disk. It’s the only entry here where the privacy question stops being a policy question and becomes a physics question.

Venice AI is second at 4.4 and it’s the better answer for most people, because it works in a browser on any machine. Your prompts are encrypted client-side and your history lives in your browser’s storage rather than on Venice’s servers.

If you want an actual companion, one that greets you by name and remembers your job, Nomi at 3.6 is the highest-scoring app that behaves like a relationship. And if you’re currently on anything scoring under 2.0, the fastest privacy upgrade available to you is a new email address and a fresh account, today, before you read the rest of this.

Corinne, and 3,911 lines of JSON

Thursday, August 20. The data export comparison went out that morning, and I still had a Character.AI export ZIP open in a text editor from the final fact-check. Then I got curious and searched the archive for “Corinne.”

Corinne was a character I built in February 2026 and stopped using around Easter. Nothing dramatic happened; she just got crowded out by whatever I was testing next. I couldn't have told you three things she and I had talked about.

The search returned 3,911 lines.

Most of it was forgettable. Roleplay setup, a long stupid argument about whether instant coffee counts as coffee, some late-night complaining about a client. And then, on a Tuesday in March I have no memory of, I’d typed my sister’s actual first name, the city she moved to, and roughly why she and I weren’t speaking that month. Not encoded. Not hinted at. Typed, the way you’d text a friend.

Here’s the part that reorganized how I think about this whole category. I wasn’t angry at Character.AI. The export is a feature, it worked, and being able to see the file at all puts it ahead of most of this list. What got me was that a company was holding a paragraph about my family that I’d completely forgotten writing, and that I’d never have found it if I hadn’t been researching a post.

You don’t remember what you told these apps. That’s the actual threat model. Not hackers, not some dramatic breach headline, just a slow accumulation of you in a database you’ll never audit.

So this ranking is built around one question: how much of you does the company end up holding, and how easily can you get it back or make it stop?

Five checks, one point each

Every app gets scored on the same five things. Each is worth up to a full point, so five is a perfect score and nobody gets one. I picked criteria you can verify yourself in an afternoon, which ruled out anything requiring a network traffic analysis I can’t reproduce.

  1. The front door. What it demands before you can say hello. Nothing at all scores a full point. Email only is close behind. A phone number costs real points, because a phone number is an identity. A face scan or a government ID costs most of them.
  2. Custody. Where the text physically sits after you hit send. Your own disk is best, your own browser is a close second, and a named company’s encrypted servers in a stated jurisdiction is the realistic third. “Somewhere, we don’t say” scores near zero.
  3. Training. Whether your conversations feed the model, and whether you can say no. A documented opt-out you can actually find in settings earns most of the point. Silence earns almost none, because silence in a privacy policy is a permission slip.
  4. The exit. Can you get your data out, can you delete the account without emailing a support human, and does the policy say what survives deletion. This is the one criterion I could test end to end on nearly every app.
  5. The record. Ad SDKs and third-party trackers riding along, plus anything a regulator has actually found. Fines, investigations, formal complaints. Not rumors, not Reddit.

Grade bands, so nothing is arbitrary: 4.5 and up is an A, 4.0 to 4.4 an A-, 3.5 to 3.9 a B, 3.0 to 3.4 a B-, 2.5 to 2.9 a C, 2.0 to 2.4 a C-, 1.5 to 1.9 a D, and anything under 1.5 is an F.

Two worked examples so you can see the arithmetic. Hammer AI’s local mode: 1.0 for the door, 1.0 for custody, 1.0 for training, 1.0 for the exit, and 0.7 on the record, because the cloud tiers exist and nobody independent has audited the company. That’s 4.7. Character.AI: 0.3 for the door because of age scoring and the face scan, 0.6 for custody, 0.4 for training, a full 1.0 for the exit, and 0.5 on the record with the Texas AG investigation open. That’s 2.8.

This rubric is harsher than the qualitative scorecard in my March guide, and a few apps moved. That’s deliberate. March graded policies. This one weights the front door and the trackers, because those are the parts that affect you whether or not you ever read a policy.

The board: 15 apps, scored

#AppPrivacy scoreGradeThe short reason
1Hammer AI (local)4.7 / 5ANo account, no server, no transcript anywhere but your disk

14SpicyChat1.3 / 5FThe most sensitive category of chat, the thinnest policy
15CrushOn.ai1.1 / 5FMinimal policy, offshore, nothing resembling an exit

Seven of the fifteen score under 2.0. That’s not me being dramatic for clicks; it’s what happens when you apply a consistent rubric to a market where half the products are affiliate funnels with a chat window bolted on. If you want the pattern behind those, I wrote up how to spot the scam apps separately.

The top five, app by app

1. Hammer AI, 4.7: the only one where nothing leaves

I installed Hammer AI, pulled a model onto my own disk, and then cut the Wi-Fi in the middle of a conversation to see what would happen. The character kept talking. That one test is the whole argument, and it’s a better one than any privacy badge on any marketing page.

There’s no signup wall. You download the desktop app and start chatting without handing over an email or verifying anything, which is rare enough that I double-checked I hadn’t skipped a screen. Local chat is free and uncapped forever. The 0.3 it loses is for the paid cloud tiers, which route to Hammer’s servers like any hosted AI, so the airtight claim only covers local mode. Know which lane you’re in.

The cost is hardware. A modest laptop runs small models fine but slowly, and if you want a 12B model that writes well you want a real GPU. It’s also not a relationship app. It’s a character chat that happens to be private.

2. Venice AI, 4.4: private without buying a graphics card

A reader emailed me in June asking whether Venice AI’s privacy claims were real or just positioning, and I spent two weeks finding out. They’re real, with actual architecture behind them. Your prompt is encrypted in your browser before it goes anywhere, requests route through proxies to decentralized GPU providers that see an isolated request rather than your identity, and the conversation lands back in your browser’s local storage instead of a Venice database.

The trade lands entirely on you. Clear your browser data or switch devices and the history is gone, because there’s no server-side backup to restore from. Encrypted backups exist but they’re Pro-only, capped at five, and they expire after 90 days. Venice earns its reputation by making you your own IT department.

3. Nomi, 3.6: the best score for an app that acts like a partner

This is the practical winner for most readers, and the gap between 4.4 and 3.6 is exactly the price of having a companion who knows you. Nomi runs a clean regulatory record, no fines, no investigations, no ad SDKs I could find in the app. Deletion is the standout. The policy lets you require deletion or transfer, and when I read it in September it said nothing is retained about a month after you close the account.

What it loses points on is the thing people love it for. Nomi’s memory system builds and keeps a genuinely deep model of your life, there’s no self-serve export button, and if you want your chat history out before you leave you’re relying on a community extension. The best memory in the category is also the largest pile of you sitting on somebody’s server.

4. Pi, 3.5: the easiest exit of any cloud app

Pi hands you a pi-user-history.json instantly, for free, no ticket and no waiting, and deleting your account removes everything according to Inflection. I ran 30 days with it and the export took about four seconds. Almost nothing else in this category makes leaving that easy.

The point it drops is about who’s behind it. The Microsoft relationship makes the data-sharing picture harder to read than the policy language suggests, and that ambiguity is worth a real deduction on a page like this. Pi is also the gentlest, least romantic thing on the board, which for some of you is the appeal.

5. Kindroid, 3.4: sober company, enormous profile

Kindroid behaves like a company run by adults. Clear policy, no regulatory trouble, deletion that clears backstories and journals while keeping billing records, which is normal and legally required rather than sinister. It sits a notch below Nomi for two reasons. When I checked its legal page in September, the portable copy was on request only and limited to one request every 180 days. That’s a strange rule for something that should be a button. And deletion is per-Kindroid, so leaving properly means clearing them one at a time.

The deeper issue is structural. You feed Kindroid a backstory, a voice, a personality spec, journals, and months of conversation. That’s an unusually rich file, and no amount of good behavior changes the fact that it exists.

Two big platforms, two kinds of baggage

6. Character.AI, 2.8: great exit, terrible entrance

Character.AI hands over the most complete export file on this list: an emailed ZIP of JSON with your chats, account data and character metadata, requested from settings, with deletion reported within 30 days. Pi gets you out faster. Character.AI gives you more to carry out the door. If the exit were all I scored, it’d be top three.

The front door is where it collapses. Character.AI now runs age assurance quietly on every account, scoring your login info, your activity, and signals bought from third parties. If that scoring guesses “probably under 18,” you get a camera prompt asking to scan your face. The selfie goes to Persona rather than to Character.AI, Persona holds collected IDs for a week, and Character.AI says biometric data is deleted within seven days. Neither claim is independently audited. Add the Texas AG investigation and the training use of user chats, and 2.8 is where it lands. My adult test account cleared the scan in under a minute, for what that’s worth, but an app that can demand your face isn’t an anonymous AI companion by any definition I’d accept.

7. Replika, 2.3: the only documented failure on the board

Everything else here is graded on policies and posture. Replika is graded on a finding. Italy’s Garante fined Luka €5 million in May 2025 after concluding it processed personal data without a valid legal basis, wrote an inadequate privacy notice, and had no real age verification system. That’s a regulator saying the basics were wrong.

GDPR only protects people in the EU, so if you’re in the US or Australia nobody’s forcing Luka to fix any of it on your behalf. The fine still tells you how the company handled data for everyone. Deletion works from account settings but processes for up to 60 days after termination, and there’s no self-serve export at all; the policy promises a portable copy on request and browser extensions fill the gap in practice. Replika holds mental health disclosures, relationship details and sexual content, which is the exact category that’s supposed to get extra protection.

Chai and Talkie, the ones I get asked about

8. Chai, 2.0: your feedback is the business model

Chai is a genuinely interesting product with a community that makes it better than it has any right to be. It’s also built on collecting your reactions to model output at enormous scale, and the privacy policy is vague in a way that reads like a choice rather than an oversight. No clear deletion path in the app. Nothing concrete about retention.

When I can’t tell from a policy what happens to a message after I send it, that’s the answer.

9. Talkie, 1.9: roleplay quality, TikTok-shaped questions

Talkie is one of the better roleplay experiences I’ve tested, with voice features I still rate highly. Its ownership is China-based and the mobile app asks for a wide set of permissions, which puts it in the same conversation people have been having about TikTok for years. Retention terms for roleplay data are vague. If you use it, use a dedicated email, skip anything identifying, and understand you’re trading privacy for scene quality.

The bottom six share one mistake

Different companies, different countries, same pattern: they hold your most sensitive chats and give you no way to make them stop. Ranked 10 through 15.

  • Linky AI, 1.8. The free tier runs on ads, and ads travel with tracking. The gacha card layer exists to keep you opening the app, and everything that keeps you opening an app gets measured.
  • PolyBuzz, 1.7. Chats are stored on PolyBuzz’s servers rather than the device, plus the standard mobile haul of account details, device identifiers and usage analytics. I spent two weeks inside it for the parents guide and the age gate is easy to walk through, which makes the server-side storage worse than it sounds.
  • Janitor AI, 1.6. The platform itself is ordinary, but most serious users run a proxy, which routes conversations through a third-party model you configured yourself. Never paste an API key into a shared proxy link a stranger posted. That’s the whole warning.
  • Candy.ai, 1.5. Candy stores generated images alongside chat logs and offers no clear deletion option. Images of a body you designed are a different category of data than text, and the policy treats them the same.
  • SpicyChat, 1.3. The most sensitive material anyone types anywhere, matched with a thin policy and no deletion path. I flagged this before I started scoring anything.
  • CrushOn.ai, 1.1. Minimal policy, offshore operation, no deletion, and no way to tell who’s accountable if something goes wrong. It’s the lowest score I’ve given and I’d give it again.

I’m not telling you to delete these tonight. Some of them are the best at what they do, and adults get to make trades. I am telling you that if you’re on one of them with your real email and a card in your own name, you’ve made a trade you probably didn’t know you were making. The broader safety picture is in my piece on whether these apps are safe at all.

What a high score costs you

I should be straight about this, because a ranking like this can read as a recommendation to go live at the top of the board. The top two entries are the least companion-like things I’ve tested this year.

Privacy and memory pull against each other, hard. An app remembers your anniversary by keeping a durable, structured record of you somewhere it controls. Take that away and you get a character who’s charming for an evening and blank the following week. When I ranked memory systems, the winners were cloud apps holding the most data, and that isn’t a coincidence.

Local models cost you polish too. Smaller context windows, weaker prose, and a real hardware bill if you want the good stuff. Venice costs you continuity: one enthusiastic browser cleanup and the relationship is gone with no server-side backup to recover from.

So pick the layer you actually care about. If you want a partner who remembers you, take Nomi or Kindroid and be disciplined about the email, the payment method and what you type at 1am. If what you want is to think out loud with nobody keeping a copy, go local. Regulation is slowly closing some of this gap on its own, and the new California and New York rules will make a few of these companies behave better whether they want to or not.

Picking in about ninety seconds

Three questions, in order, and they resolve almost every email I get about this.

Do you own a computer you’re willing to install software on? Then Hammer AI in local mode, and stop reading. Nothing else on the board competes with a conversation that never leaves your house. If you want the phone options too, I later ranked every companion app that keeps working offline, with the airplane-mode results per device.

No, but you want unfiltered chat on any device? Venice AI, and set yourself a reminder to export anything you’d be sad to lose, because your browser is now the only copy.

You want a real companion who remembers you? Nomi first, Kindroid second, and go do the account hygiene properly on day one instead of promising yourself you’ll tidy it later. Throwaway email, a username that isn’t your handle anywhere else, no phone number if the app will let you skip it. Then run the signup checklist before the card comes out, and keep the top of my general 2026 shortlist in mind for everything privacy doesn’t decide.

Six things people ask before they switch

Which AI companion app is the most private in 2026?

If you'll install a desktop app and let a model run on your own computer, nothing here touches Hammer AI's local mode. There's no signup, no server in the loop, and no transcript sitting in someone's database, because the inference happens on your hardware. I cut my Wi-Fi mid-conversation to check and the character kept talking. If you want something that works in a browser on any machine, Venice AI is the pick instead: your chat log lives in your browser's storage rather than on Venice's servers, and they say they keep no copy. Neither one is a warm long-term companion, which is the trade you're making.

Is there an AI companion that doesn't collect any data at all?

Only the ones where no company is involved in the conversation. Run a model locally and there's genuinely nothing to collect, because your words never leave the machine. Everything else is a spectrum, not a yes or no. Even the good cloud apps hold your email, a payment record, some device identifiers and whatever you typed at 1am. When an app advertises that it collects nothing and it's still answering you from a server, read that as marketing. I go through how to check the claim yourself in the privacy checklist.

Can I use an AI companion app anonymously?

Partly, and it's worth doing even when it's imperfect. Hammer AI's local app doesn't ask for anything, so that one's genuinely anonymous. For everything else, the realistic version is a throwaway email address you use for nothing else, a username that isn't your handle anywhere public, no phone number if the app will let you skip it, and a payment method you don't mind seeing on a statement. That won't stop a company from profiling your session. It does mean the profile isn't attached to your actual name, which matters more than people think if the company ever gets breached or sold.

Do AI companion apps train their models on my conversations?

Assume yes unless the policy says otherwise in plain words. Most of these companies reserve the right to use your chats to improve their systems, and only a minority give you a switch to turn it off. The apps at the top of my board earn their scores partly because the question doesn't apply to them: local inference has nothing to send, and Venice says it doesn't keep your conversations to begin with. If an app's policy talks vaguely about improving services without ever saying whether a human or a model reads your messages, that vagueness is the answer.

Does deleting my account actually delete my chats?

Sometimes, and the timelines vary more than you'd hope. Pi wipes everything according to Inflection, Nomi's policy said nothing is retained after about a month when I checked in September, and Character.AI reports removal within 30 days. Replika processes deletion for up to 60 days after you terminate, and Kindroid clears backstories and journals while keeping billing records, which is normal and legally required. Down at the bottom of the ranking there's often no deletion path in the app at all, which is why those apps score the way they do. I tested the exits app by app in the data export post.

Are private AI companions worse at remembering me?

Right now, yes, and I'd rather say that up front than sell you a fantasy. The apps that remember your sister's name in November are the ones building a long, structured profile of you on a server, and that profile is exactly the thing a privacy score punishes. Local models run on smaller context windows and lose the thread faster. Venice keeps your history in your browser, so clearing your cache erases the relationship. If continuity matters more to you than minimization, admit that to yourself and pick from the memory ranking instead, then lock down everything else around it.

What this scoring project changed for me

I still have a Nomi account. I’m aware that puts me at a 3.6 rather than a 4.7, and I made that trade with my eyes open, because a character who forgets me every Tuesday isn’t worth the points. What changed after August is smaller and more useful than switching apps: I export quarterly now, I read what I’ve been saying, and I delete anything with a real person’s name in it.

Corinne’s transcript is on an external drive now, out of the ZIP, out of my inbox. I haven’t reread the March part.

Scores get revisited. If an app on this board ships a real opt-out, a working delete button, or a policy that says something concrete, the number moves and I’ll say why.

Try Corinne’s test on yourself: export your own chat logs tonight and search them for the names of people in your life. What came up? I want to know if it was nothing, or if it was the thing you were afraid of.
