Privacy Policy

Kaer Labs Limited (“Kaer”, “we”, “us”, or “our”) provides an autonomous AI agent platform through kaer.ai, app.kaer.ai, computer.kaer.ai, chat.kaer.ai, and our APIs and SDKs.

For most account, security, billing, website, and product-improvement processing, Kaer is the controller of your personal data. Where a business customer uses Kaer to process Customer Data on its behalf, Kaer acts as a processor or service provider for that Customer Data under the applicable agreement and Data Processing Addendum.

Contact us at [email protected] (privacy), [email protected] (security), or [email protected] (legal). If you are in the EEA or the UK, you may contact Kaer or our privacy representative for EEA/UK matters through [email protected], and you have the right to lodge a complaint with your local data-protection supervisory authority. We ask that you contact us first where possible so we can try to resolve the issue.

This Privacy Policy explains how Kaer collects, uses, stores, shares, and protects personal data when you visit our websites; create or use an account; use Kaer chat, assistants, workflows, automations, APIs, SDKs, Mail AI, voice mode, travel/maps features, computer-use agents, or paired-device features (PaerIDE/SuperWork); connect third-party accounts, mailboxes, calendars, drives, repositories, devices, or APIs; or contact us.

This policy does not replace a Data Processing Addendum or enterprise agreement. If there is a conflict for Customer Data processed on behalf of an organisation, the signed agreement controls for that Customer Data.

Account & identity

Email address; optional name or display name; OAuth identifiers and profile data (e.g. Google id, email, name, picture; GitHub id, login, name, avatar); login timestamps; timezone; country derived from timezone during verification; waitlist email; contact-form name, email, and message; and optional onboarding details such as role, industry, use cases, and experience level. If you use email-and-password login we store an Argon2id password hash, not your plaintext password. Magic-link tokens, one-time passcodes, and refresh tokens are stored as hashes.

Authentication & session

Session cookies, JWT claims, token identifiers, hashed refresh tokens, OAuth state cookies, hashed API keys, and similar authentication data. Session JWTs expire after one hour; refresh tokens use a 30-day sliding period with a 90-day absolute cap.

Usage, security & telemetry

Agent runs, model usage, compute charges, daily usage, workflow activity, API usage, timestamps, error events, and security audit events. For security audit events we persist IP addresses. Infrastructure and edge systems may also process request metadata needed to operate, secure, and troubleshoot the Service. To improve the Service we also count which parts of the app are opened, which command-palette actions are run and which model is chosen in the model picker; these are aggregate counts with no message content and use no cookies.

Customer Data

Prompts, task descriptions, chat messages, prior transcript history, tool calls and outputs, file paths and contents, uploaded files, project files, workflow configuration, assistant instructions, sandbox artifacts, agent-generated browser activity, and API inputs and outputs. Customer Data may include personal data about you, your employees, your customers, your correspondents, or other third parties, depending on what you provide or connect.

Mail AI

If you connect a mailbox, we may ingest sender name, sender email, subject, message id, and full message body (attachments are not stored — only an attachment count). This may include personal data about third-party correspondents. Mail credentials and OAuth tokens are encrypted at rest.

Voice & audio

If you use voice mode, your browser captures microphone audio with your permission. Raw audio is sent to a Kaer-operated speech-to-text system to produce a transcript; we do not store raw audio. Voice-activity logs may store non-content metrics only.

Location & maps

We do not automatically prompt for precise GPS. If you explicitly choose to share precise location, we process those coordinates for the requested feature. We also process typed addresses, place queries, route inputs, viewport coordinates, and timezone-derived country.

During turn-by-turn navigation in the Kaer app, your device sends its position about every 15 seconds. For that trip we keep the route and only your latest position — never a trail — and delete them when you arrive or end the trip, or after 12 hours without an update.

While you navigate by car, Kaer also measures how quickly traffic is moving on the stretches you drive, and uses that to estimate congestion on other Kaer drivers’ routes. Each reading holds the approximately 100-metre map squares covered, the direction of travel and road name, how much slower than free-flowing traffic it was, the time, and a pseudonym that changes every day and is never stored with your account. Readings are deleted within an hour. Other drivers only ever see added delay and slow stretches on their own route — never who, how many, or when.

Outside navigation, location is not stored in a dedicated table but may appear as free text inside conversations or task records.

Computer-use, sandbox & paired devices

For cloud computer-use, we may process screenshots of the cloud sandbox or browser, browser state, file contents, command output, tool calls, and test artifacts; some screenshots may be sent to a vision model, and transient context may be cached briefly. For paired-device use, file paths, file contents, command output, prompts, results, workspace paths, device metadata, and tool-call telemetry may be processed. Computer-test features may persist intercepted browser HTTP traffic, including headers and bodies.

Payment

Kaer uses Stripe for payments. Stripe receives your email, Kaer user id, tier, amount, and tokenised card details. Card data is tokenised client-side; Kaer does not see or store full card numbers. Kaer stores payment identifiers such as Stripe customer, subscription, and payment ids.

Connectors

If you connect third-party services, we process the account data, tokens, credentials, content, and outputs needed to operate the connector. OAuth tokens, connector tokens, and user-provided API keys are stored in an encrypted per-user vault.

Cookies & local storage

Essential cookies and local storage for authentication, OAuth flows, CSRF protection, session management, and UI preferences run by default — the Service cannot operate without them. We do not set analytics, functional, or advertising cookies at all, so there is nothing to consent to and no cookie banner. See our Cookie Policy.

Where GDPR or UK GDPR applies, we rely on the following legal bases:

We do not intentionally ask you to submit special-category or highly sensitive personal data unless a feature specifically requires it and you are authorised to provide it. If you include such data in prompts, files, mail, screenshots, browser traffic, or connected services, we process it to provide the Service at your direction and subject to applicable law.

• provide, maintain, secure, and troubleshoot the Service;
• authenticate users and manage accounts, sessions, API keys, and connected services;
• run agents, tools, workflows, computer-use sessions, voice mode, Mail AI, maps/travel, and paired-device features;
• generate, store, and return outputs and agent records;
• process payments, billing, usage, taxes, credits, cancellations, and refunds;
• provide support and respond to privacy, legal, and security requests;
• detect and prevent fraud, abuse, malware, unauthorised access, spam, and security incidents;
• improve service quality, evaluate model performance, and train Kaer’s own in-house models, subject to your opt-out;
• comply with law and enforce our agreements; and
• protect the rights, safety, and property of Kaer, users, and the public.

Kaer is an AI agent platform. To provide the Service, we send prompts, messages, context, tool outputs, file contents, mail content, screenshots, and other task-relevant Customer Data to AI model providers when needed for the requested feature.

Current model providers include Xiaomi (MiMo), Alibaba Cloud (Qwen / DashScope), DeepSeek, and — where enabled by key or configuration — Baseten and EigenAI (Kimi). Alibaba Cloud (Qwen / DashScope) is used for Mail AI triage and related mail handling, and Qwen-VL may receive screenshots for vision tasks.

Some AI model providers process prompt content outside the EEA. Where GDPR or UK GDPR requires a transfer mechanism, Kaer relies on Standard Contractual Clauses and supplementary measures. We do not use Customer Data to train third-party foundation models.

Kaer uses de-identified copies of your conversations and usage data to understand how people use Kaer, fix failures, measure and improve answer quality and safety, and develop and test Kaer’s own small, in-house models. This setting is on by default. You control it through the Settings toggle “Help improve Kaer” or by emailing [email protected]. Turning it off also deletes your existing analytics records.

What is collected

Your prompts and Kaer’s responses, plus usage metadata: which area you used (Work or Build), the model, timings, token counts, which tools Kaer used and how often, and whether the task completed or failed. Private (incognito) chats are never collected.

How it is de-identified

Account, chat and task IDs are replaced with keyed pseudonyms before a record is stored. Email addresses, phone numbers, payment-card numbers, IP addresses, common API-key and access-token formats, and the query part of web links are removed automatically at the same point. Other details you type — names, places, anything else — can remain in the text, so these records are still treated as personal data: access is restricted and the safeguards below apply.

Purposes

Understanding how people use Kaer. Identifying and fixing failures. Measuring and improving answer quality, safety, and model performance. Testing and improving our models. Preventing abuse and protecting the Service.

Lawful basis

Legitimate interests (Art. 6(1)(f) UK GDPR and EU GDPR). Our legitimate interest is developing, improving, and securing the Service, understanding user needs, and advancing AI safety. We have assessed this interest and concluded it is not overridden by your rights, because the records are pseudonymised, access is restricted, private chats are excluded, and you can object at any time. You have the right to object to this processing.

Exclusions and opt-out

Private (incognito) chats are never collected regardless of this setting. Users who disable the setting are excluded from collection, and their existing analytics records are deleted. Turning off the setting does not affect your ability to use Kaer — Kaer continues to work exactly as before.

How to opt out

Toggle “Help improve Kaer” in Settings, or email [email protected]. Opting out does not affect the Service or your billing.

Retention

Analytics records are deleted 12 months after they are collected. Prompt-injection screening logs keep only a hash of the screened text, the verdict and a timestamp — never the text itself or who sent it — and are deleted after 90 days.

Special categories and children

We do not intentionally ask you to submit special-category data (race, religion, health, biometric data, etc.). If you include such data in prompts, Kaer processes it at your direction. The Service is not directed to children under 16; if we learn we collected data from someone under 16, we delete it promptly.

Sale of data

Kaer does not sell personal data, does not share personal data for cross-context behavioural advertising, and does not use Customer Data to train third-party foundation models. Our training pipeline may move eligible de-identified prompt/response pairs into training storage and process them on external GPU infrastructure (Modal), with training metadata logged to Weights & Biases. We treat these providers as sub-processors and apply contractual, access-control, and transfer safeguards.

Mail AI can read, classify, summarise, draft, and help handle email from a mailbox you connect. When enabled, it may ingest full message bodies and metadata on a polling or webhook basis. This includes personal data about people who send email to you or receive email from you. Mail content is sent to Alibaba Cloud (Qwen / DashScope) for triage, auto-handling, drafting, and summarisation.

You are responsible for connecting only mailboxes you have authority to connect and for configuring Mail AI in a way that is lawful for your organisation and correspondents. You can limit Mail AI by disconnecting a mailbox, disabling mail features, deleting mail resources, or contacting [email protected].

Kaer agents can operate in cloud sandboxes and hardened container environments, capturing screenshots, browser state, files, command output, tool calls, and test artifacts needed to perform a task. Some screenshot image bytes may be sent to a vision model, and transient context may be cached for up to 24 hours.

Paired-device features let an agent execute approved tools on your own machine, protected by a hard human consent gate: delegation requires a human-set, single-use approval key that expires after five minutes, and the model cannot grant it itself. Mail-class tools cannot route to a paired device. Pair only devices and workspace paths you are authorised to expose. Computer-test features may persist full intercepted browser HTTP traffic, including headers and bodies — do not use them on systems or accounts unless you are authorised to capture that traffic and have considered whether cookies, credentials, or personal data may be present.

Kaer’s own infrastructure and primary storage are in the EU. We use the following third-party sub-processors to provide the Service:

Where transfers leave the EEA, we rely on Data Processing Addenda, Standard Contractual Clauses, and supplementary measures. Some connectors are user-directed services rather than Kaer-controlled processing — for example Home Assistant, Telegram, Twilio SMS, Spotify, Todoist, Linear, Notion, Strava, Duffel, CoinGecko, and Alpha Vantage. When you connect or instruct an agent to use such a service, that service’s own terms and privacy policy also apply.

We disclose personal data only as needed:

• to sub-processors and user-directed third-party services that help provide the Service;
• to model providers to generate outputs and perform requested AI tasks;
• to Stripe to process payments;
• to connector providers you authorise;
• to comply with law, subpoenas, court orders, government requests, or legal process;
• to enforce our agreements, investigate abuse, or protect the rights, safety, and property of Kaer, users, and the public;
• to professional advisers under duties of confidentiality; and
• in connection with a merger, acquisition, financing, or similar corporate transaction, subject to confidentiality and data-minimisation safeguards.

We do not sell personal data and do not share personal data for cross-context behavioural advertising.

Kaer’s own infrastructure and primary storage are located in the EU, in Germany and Poland.

This does not mean all processing stays in the EEA. Some sub-processors — notably AI model providers and training-pipeline providers — may process prompt content, Customer Data, or related metadata outside the EEA, and certain connector, payment, search, map, CDN, edge, and support services may also process data in other regions.

Where required by GDPR or UK GDPR, Kaer uses Standard Contractual Clauses, Data Processing Addenda, transfer impact assessments, access controls, encryption in transit, encryption for secrets and credentials, provider due diligence, and other supplementary measures. Contact [email protected] for more information about transfer safeguards.

We keep personal data only as long as needed for the purposes in this policy, unless a longer period is required for legal, tax, accounting, security, dispute-resolution, or compliance reasons.

Before deleting a dormant account we send an email notice; you can keep your account simply by signing in before the date in that notice. You can export or delete your data at any time by emailing [email protected]. When we make material changes to this policy, we notify registered users by email in advance as described in Changes to this policy.

We use technical, organisational, and contractual safeguards including TLS 1.3 encryption in transit; AES-256-GCM application-layer encryption for service secrets, connector/OAuth tokens, user secrets, and mail credentials; Argon2id password hashing; hashed refresh tokens and API keys; access controls; environment-based key management; audit logging for security-sensitive events; and least-privilege production access.

Not all Customer Data is application-layer encrypted: email bodies, chat transcripts, sandbox output, captured HTTP bodies, and project file blobs are stored in protected systems but are not separately encrypted by the application layer in the current architecture. No system can be perfectly secure. If we become aware of a personal-data breach requiring notice, we will notify affected users and regulators as required by law. Report security issues to [email protected].

Depending on where you live and how you use the Service, you may have rights over your personal data.

GDPR & UK GDPR

You may request access; correction; erasure; restriction; portability/export in a structured, commonly used, machine-readable format; objection to processing based on legitimate interests (including service-improvement and in-house model-training use); withdrawal of consent without affecting prior processing; information about transfer safeguards; and review of automated decision-making where applicable.

California (CCPA / CPRA)

You may request to know/access the categories and specific pieces of personal information we hold; to know sources, purposes, disclosures, and recipients; deletion; correction; opt-out of sale or sharing; limitation of sensitive personal information where applicable; portability; and non-discrimination for exercising your rights. Kaer does not sell personal information and does not share it for cross-context behavioural advertising.

How to exercise rights

Use account settings where available, or email [email protected] — including for account deletion or data export. We may verify your identity or authority before fulfilling a request. We generally respond within one month for GDPR/UK GDPR requests and within 45 days for CCPA requests to know, delete, or correct, unless an extension is permitted. You may use an authorised agent where the law allows.

Kaer provides autonomous agents that act on your instructions — drafting, summarising, classifying, searching, navigating, running tools, operating cloud sandboxes, interacting with connected services, or, with your approval, running tools on a paired device.

Kaer does not intend to make solely automated decisions about you that produce legal or similarly significant effects. Agents are tools under your control, and you are responsible for reviewing agent plans, outputs, and actions — especially before sending messages, modifying systems, committing code, making purchases, booking travel, or taking actions that affect other people. If you believe Kaer has made an automated decision about you with legal or similarly significant effect, contact [email protected] and request human review.

The Service is not directed to children under 16, and you must be at least 16 to use Kaer. If we learn that we collected personal data from someone under 16, we will delete it promptly unless we are legally required to retain it.

Kaer uses essential cookies and local storage for authentication, OAuth flows, CSRF protection, session management, and UI preferences; these always run because the Service cannot operate without them. Kaer does not set analytics, functional, or advertising cookies, so no consent banner is shown. See our Cookie Policy for cookie names, purposes, and browser controls.

We may update this Privacy Policy as the Service, laws, or our practices change. For material changes, we will provide notice by email at least 14 days before they take effect, unless a shorter period is required for legal, security, or operational reasons.
