Frequently Asked Questions

Q: Can Maexry read my emails?

Mathematically impossible. Your emails are stored only on your device, and AI classification runs through your own API keys — we never see your content. When syncing across devices, only encrypted blobs touch our servers — and we don't have the keys to decrypt them. Our zero-knowledge architecture means we cannot access your email content.

Q: What if Maexry gets hacked?

There's nothing to hack. We don't store your emails, API keys, or encryption keys. A breach of our servers would reveal... encrypted noise. Your master key is hardware-bound to your device's Secure Enclave, not stored on our servers.

Q: What if I lose my device?

Your master key is hardware-bound to that specific device and cannot be extracted. For new devices, you'll re-enter your master password once to decrypt your sync seed and regenerate your keys. Your encrypted sync data remains safe — it's useless without your master password.

Q: Can law enforcement access my data?

We cannot provide what we don't have. Your emails never touch our servers, so there's nothing to subpoena. Even if ordered to hand over data, we only have encrypted blobs that are mathematically impossible to decrypt without your master key.

Q: How do I know this is true?

We use industry-standard encryption (AES-256-GCM) with OWASP-recommended key derivation (Argon2id). Our zero-knowledge architecture means there is nothing to trust — monitor your network traffic and verify for yourself that no email content leaves your device.

Q: Why is Maexry so much cheaper?

We use a BYOK (Bring Your Own Key) model. You provide your own AI API key from Gemini, OpenAI, or Anthropic. You pay them directly based on actual usage — typically $0.50-$1.00/month. No expensive subscriptions, no middleman markup.

Q: Do I get future updates with the $19.99 Base purchase?

Yes. Your one-time Base purchase includes every future update, new feature, and maintenance release at no additional cost — for as long as Maexry is in operation. No upgrade fees. No version gating.

Q: Does Maexry process my emails in the cloud?

Classification and summarization run through the AI provider you choose (your own API key, or your own Ollama instance if you run one). When Maexry classifies your email, your device sends it to that provider, governed by their privacy policy. Storage and key management are always on your device.

Q: Can Maexry employees read my emails?

No. There is no server-side code path that accesses email content. Encryption keys exist only in your device's Secure Enclave. We have no decryption capability.

Q: What if your sync server is breached?

Attackers would find Dark Blobs (encrypted binary), device UUIDs, and sync timestamps. No email content, no subjects, no senders, no categories. The encryption keys are on your device, not our server.

Q: Why do I need an API key?

Maexry classifies your email into 8 categories using an LLM. You provide the LLM — either your own API key (BYOK) or your own Ollama instance (Bridge). This means you control the AI provider, the cost, and the data flow.

Q: What is the Bridge Engine?

Bridge connects Maexry to your local Ollama instance. Classification runs on your own hardware, on your own network. Zero cloud dependency. This is the option for users who want fully local intelligence.

Q: How is this different from other email apps?

Most AI email apps send your email to their cloud, process it with their AI, and store it on their servers. When classification runs on-device, nothing is sent anywhere. When you use a cloud provider, the email Maexry classifies is sent to that provider, governed by your provider's privacy policy. We never see your email content.

Q: What platforms does Maexry support?

Maexry runs natively on iOS (iPhone and iPad) and macOS. Android and Windows are coming soon. There is no web app — local AI processing requires direct hardware access, so Maexry is native-only by design. For fully local AI, run Ollama on the same device — or point Maexry at an Ollama server on your own network (you enter its address in Settings). Maexry connects to that address directly: there's no automatic phone-to-desktop pairing or discovery, and it can't reach a server outside your local network.

Q: How do I manage or cancel my subscription?

Open Maexry → Settings → Subscription → Manage Billing. This opens your Stripe billing portal, where you can update your payment method, switch between plans, or cancel. Cancellation takes effect at the end of your current billing period — you keep full access until then. After a monthly subscription cancels, sync and AI stop — existing emails remain readable on-device. Annual subscribers fall back to permanent Base access (BYOK/Ollama forever). Nothing is deleted.

Q: Can I use Maexry on multiple devices?

Yes. On Base ($19.99 one-time), install Maexry on as many devices as you want. Each device runs independently with its own local database — no sync between them. On Pro ($3.99/month or $34.99/year), your settings and preferences sync across devices via end-to-end encrypted blobs we cannot decrypt — Pro is standalone, no separate Base purchase needed.

Q: Can I export my data?

Your data lives in an encrypted SQLite database on your device. Maexry does not keep a cloud copy — you own the only copy. If you delete the app, the local database is permanently removed. We cannot recover your data for you — that's the point of zero-knowledge architecture.

Q: What happens after my free trial ends?

After the 14-day trial, sync and AI stop — existing emails remain readable on-device. Your data stays on your device untouched. Nothing is deleted or locked. You can buy at any time to reactivate: Base is $19.99 once (bring your own AI key), or subscribe to Pro ($3.99/mo) for standalone access to everything. Annual Pro subscribers get permanent Base access if they cancel later.

Q: How does Ollama / local AI work with Maexry?

Ollama lets you run open-source AI models entirely on your own hardware. Install Ollama on your Mac or PC, pull a recommended model, and point Maexry to your local Ollama instance (a localhost URL in Settings). Every AI classification then runs on your machine — zero network calls, maximum sovereignty. The tradeoff: it requires a reasonably powerful computer with 8 GB+ RAM.

Q: What is the Maexry MCP server?

Maexry includes a built-in Model Context Protocol (MCP) server that lets AI assistants — Claude, OpenAI, Gemini, and any MCP-compatible agent — read and act on your email directly. It runs on localhost only, requires a Bearer token, and auto-starts after vault unlock. Your email never leaves your device to reach the MCP server; the server is local software, not a cloud service.

Q: Which AI assistants can I connect via MCP?

Claude Code, Claude Desktop, OpenAI Assistants, and Gemini CLI are all supported. Any agent or tool that speaks the MCP 2025-06-18 protocol over Streamable HTTP can connect. Maexry's Settings → Integrations → MCP Server provides pre-filled config snippets for each supported platform.

Q: What can an AI assistant do via MCP?

A connected assistant has access to 25 tools: fetching emails and threads, searching with filters, reading categories and action cards, drafting replies, archiving, deleting, labeling, moving messages, batch operations (up to 50 messages per call), listing and downloading attachments, and writing Sovereign Vault notes. Every tool call enforces per-account access controls.

Q: Is MCP access secure?

Yes. The server binds exclusively to 127.0.0.1 — external hosts cannot reach it. Each session requires a Bearer token generated on-device. Tokens are revoked automatically when you lock your vault or quit Maexry. No MCP traffic transits Maexry's servers.
