Pick mandatory-login cloud suites (ChatGPT, Claude, Gemini, Copilot) when you want server-side chat history synced across Windows, Android, and shared web browsers. Pick GPT Realtime Assistant ($9.99/mo across iPhone, iPad, and Mac) when you want **zero email/password/phone registration**: the app starts immediately with a silent device account (plus optional Sign in with Apple), stores all transcripts and Tasks locally on your device, and never links your conversations to a marketing email list.
| Identity & Privacy Check | GPT Realtime Assistant (v1.2) | Mandatory-Login AI Apps (ChatGPT / Claude / Gemini) |
|---|---|---|
| Email address required to use app | No — zero email/password sign-up form | Yes — requires email, Google, Microsoft, or Apple login |
| Personal SMS phone-number verification | Never requested | Frequently required during account creation |
| Optional Sign in with Apple (Hide My Email) | Supported optionally for cross-device credit linking | Supported as one login option alongside email/SMS |
| Server-side transcript & attachment database | None — Arte Soft backend never receives audio or transcripts | Default cloud conversation storage tied to user ID |
| Cross-platform web / Windows / Android sync | No cloud sync — transcripts stay strictly on each Apple device | Yes — full cloud sync across browsers & OSes |
| 100% offline zero-network AI option | Yes — Whisper Large v3 Turbo + Qwen 3 8B on Apple Silicon Mac | No — requires authenticated cloud session |
Why Silent Device Provisioning Respects Your Time and Identity
When you download an app from the Apple App Store, Apple already handles fraud prevention and payment processing via Face ID or Touch ID. Forcing you to type an email address, wait for a 6-digit OTP code, and hand over your mobile phone number just creates a second identity graph to breach or market to.
GPT Realtime Assistant provisions a silent anonymous account automatically on launch so your Apple ID handles subscription entitlement while your personal email stays out of another database.
The Tradeoff of Zero Cloud Sync: Own Your Backups
Honest engineering means stating the flip side of local-only storage: because GPT Realtime Assistant does not upload your transcripts, Projects, or Tasks to an iCloud or web server, a session recorded on your iPhone will not magically appear on your MacBook—and deleting the app deletes its local sandbox data unless you export important notes first.
| Data Category | Handled by Arte Soft Backend? | Where It Actually Lives |
|---|---|---|
| Anonymous / Apple-linked account ID & credit balance | Yes — minimal ledger to meter 2,000 monthly credits | `assistant-api.wonek.com` (deletable on request) |
| Apple In-App Purchase receipt validation | Yes — verifies active subscription & top-up packs | Apple App Store + minimal receipt status |
| Payment card / billing address | Never seen by Arte Soft | Handled 100% by Apple In-App Purchase |
| Live voice audio, photos & window captures | Never sent to Arte Soft backend | Streams directly from device to OpenAI Realtime API (or stays in Mac RAM offline) |
| Full transcripts, Projects, Tasks, Notes & Schedules | Never synced to Arte Soft cloud | 100% local storage on your iPhone, iPad, or Mac |
Simple Account Deletion Whenever You Want
Even the minimal backend credit ledger can be wiped completely by emailing `office@arte-soft.com`.
| Priority | Recommended Choice | Why It Wins |
|---|---|---|
| Privacy-conscious professional avoiding email/SMS profiling | GPT Realtime Assistant | Apple IAP billing + silent device account + local-only transcripts |
| Air-gapped legal, medical, or executive notes on Mac | GPT Realtime Assistant (Offline Mac Mode) | Whisper + Qwen 3 8B process speech locally with Wi-Fi off |
| Logging into chat threads from public library or work PCs | Cloud-Login AI App | Browser login pulls down server-stored history anywhere |
| Fastest airport arrival translation with zero sign-up wall | GPT Realtime Assistant | Subscribe via Face ID and start 58-language translation in seconds |
