Overview

Crypton uses artificial intelligence in two distinct ways. Platform AI runs on self-hosted infrastructure we control and is not optional for SMS abuse prevention. Crypton AI (Chat and the API) is an optional product you turn on: prompts are sent to Seeweb S.r.l. in Italy for inference and are not retained by that provider after the reply. We do not use OpenAI, Google, Anthropic, or similar US labs for Crypton AI. We still do not use AI for customer support.

For broader data handling practices, see our Privacy Policy. PRIVACY POLICY

Outgoing SMS Content Filter

Outgoing SMS messages sent through Crypton phone numbers are screened by an AI content filter before delivery.

Data Handling

• Messages that pass screening are not retained by the AI filter
• Blocked messages are encrypted at rest and retained so you can see them in your conversation, and so our team can review them if you appeal
• You are not charged for blocked messages
• No third parties are involved in the SMS screening process

Internal Content Translation

Crypton uses a self-hosted TranslateGemma model to translate Crypton-authored content into other languages.

Optional Crypton AI (Chat and API)

Crypton Chat and the OpenAI-compatible Crypton AI API are optional. You must have an account. Nothing is sent to the inference provider until you send a Chat message or call the API.

How inference works

• Crypton is the subscriber. We issue our own Chat session tokens and API keys. You authenticate only with Crypton credentials.
• Prompts and completions are proxied to Seeweb S.r.l. on EU GPUs in Italy. Default retention at the provider is zero. A third-party zero-data-retention certificate is dated 24 July 2026.
• Crypton does not log prompt or completion bodies on the gateway. We store usage metadata only (model, token counts, cost, timestamps) for billing and abuse prevention.
• Chat history is a separate feature: after the reply, we may store Halite-encrypted ciphertext on Crypton until you delete the thread. You can start a chat that is not saved. Encrypted history is not the same as inference retention.
• Inference runs in the EU. Crypton is a UK company (Rinzler Labs, Scotland). Billing metadata is retained under UK law.

Acceptable use

• You must not use Crypton AI for unlawful content. We pass through the upstream acceptable-use rules.
• We may suspend keys or Chat if we detect abuse, including attempts to exhaust the free allowance or bypass billing, as described under Suspension and Termination in our Terms.

What We Do Not Do

• We do not train AI models on your messages or personal data
• We do not use AI chatbots for customer support
• We do not send SMS, email, or account data to external AI APIs. Optional Crypton AI is the only user-initiated exception, and only Seeweb is used for that product
• We do not use AI to read, analyse, or monitor incoming SMS messages
• We do not use AI for advertising, profiling, or behavioural tracking

Your Choices & Appeals

If your outgoing message is blocked by the content filter, you can revise and resend it. Blocked messages appear in your conversation so you know what was held back. You can delete Crypton Chat threads at any time. You can revoke API keys from your dashboard.

If you believe a message was blocked in error, open a support ticket from your account or reach us via SimpleX Chat to appeal. Our team will review the block and respond as quickly as possible.
