Privacy Policy

Effective date: November 13, 2026
Last updated: November 13, 2026

This Privacy Policy explains how Jabberware LLC ("we," "us," or "our") collects, uses, shares, and protects information when you use the Known4 mobile applications for iOS and Android, the Known4 web application, and related services (together, the "Service").

By creating an account or using the Service, you acknowledge that you have read this Privacy Policy. If you do not agree with it, please do not use the Service.


1. WHO WE ARE
Known4 is a professional collaboration platform that connects individuals and companies for job management, messaging, document sharing, and bidding. The data controller responsible for your information is:

Jabberware LLC
Email: jabberwarellc@gmail.com


2. INFORMATION WE COLLECT

2.1 Information you give us
Account information. When you sign up we collect your first and last name, email address, and a password. We never store your password in readable form; we store only a one-way cryptographic hash of it.

Profile information. You may choose to add a job title, phone number, profile picture, professional role (for example, owner, general contractor, engineer, subcontractor, vendor, or architect), education history, work experience, skills, certifications (including certificate files), and industry classification codes (such as CSI MasterFormat codes).

Company information. If you create or manage a company profile, we collect the company's name, "doing business as" name, Employer Identification Number (EIN), addresses and office locations, business phone, support email, website, logo, description, divisions, and industry codes. We also record which users are members or administrators of a company and the status of requests to join it.

Content you create or share. This includes jobs and projects; job invitations and assignments; chat messages; photos, videos, voice recordings, and documents you attach to messages or jobs; reactions, polls and votes, pinned messages, and bookmarks; document versions and approval requests; and requests for proposals (RFPs), bids, proposals, solicitations, and awards.

Communications with us. If you contact us, we keep the content of your message and our reply.

2.2 Information collected automatically
Device and notification information. To deliver push notifications, we collect a push-notification token for each device or browser you sign in from, along with the platform type (iOS, Android, or web).

Activity and presence information. To run real-time messaging, we record when you were last active, whether you are currently online, when you are typing in a conversation, and whether messages have been delivered to and read by you. Other participants in a conversation can see some of this information (for example, read status and typing indicators).

Technical information. Like most online services, our servers and hosting providers may automatically log technical data such as your IP address, request times, and error information, for security and troubleshooting.

Authentication tokens. We issue access and refresh tokens to keep you signed in. They are stored on your device (in app storage on mobile, or in your browser's local storage on the web) and on our servers.

We do not use third-party advertising, analytics, or cross-app tracking tools, and we do not collect your precise location, your device contacts, or your browsing history.

2.3 Device permissions
The app asks for the following permissions only when you use a feature that needs them. You can decline or revoke them at any time in your device settings; the related feature will then be unavailable.

•  Camera: To take photos or videos to attach to messages or use as a profile or company picture
•  Microphone: To record voice messages and video attachments
•  Photo library: To choose photos and videos to attach, and to save photos you take in the app
•  Notifications: To alert you about new messages, invitations, and account activity

2.4 Information from third parties
App stores. If you buy a subscription in the iOS or Android app, Apple or Google processes the payment. They send us transaction identifiers, the product purchased, and subscription status (active, renewing, in a grace period, expired, or refunded). We do not receive your card number or other payment details.

Stripe. If you subscribe on the web, or a company sponsors your subscription, payment is processed by Stripe. We receive a Stripe customer identifier, subscription identifier, and payment status. We do not receive or store full card numbers.

Cloud storage providers (optional). If you choose to connect a Dropbox, Microsoft OneDrive, or Google Drive account to share files in chat, that provider sends us an authorization token, your account identifier and email address, and the permissions you granted. We use these only to let you pick and share files you choose. We store the tokens in encrypted form, and you can disconnect at any time.

Other users and companies. Other users may give us information about you, for example when a company administrator invites you to a job, sends you a subscription sponsorship, approves or removes your company membership, or mentions you in content they share.


3. HOW WE USE INFORMATION
We use information to:

•  Provide the Service: create and manage your account, display profiles and companies, run jobs, chats, document sharing, and bidding workflows, and deliver notifications.
•  Process subscriptions: confirm purchases with Apple, Google, or Stripe, determine which features you're entitled to, and manage company-sponsored subscriptions.
•  Keep the Service secure: authenticate you, verify that you're allowed to see a company's or job's data, prevent fraud and abuse, and investigate security incidents.
•  Communicate with you: send service messages such as password-reset codes, invitations, and notifications about activity relevant to you. We do not send marketing emails unless you've agreed to receive them.
•  Support and improve the Service: respond to your requests, troubleshoot problems, and maintain and develop features.
•  Meet legal obligations: comply with laws, respond to lawful requests, and enforce our Terms of Service.

Legal bases (EEA, UK, and Switzerland). Where these laws apply, we rely on: performance of a contract (providing the Service you signed up for); legitimate interests (security, fraud prevention, improving the Service, and supporting the companies you work with), balanced against your rights; consent (device permissions and optional cloud-storage connections, which you can withdraw at any time); and legal obligation (tax, accounting, and responding to lawful requests).

We do not sell your personal information, share it for cross-context behavioral advertising, or use it to make decisions about you based solely on automated processing that produce legal or similarly significant effects.


4. HOW INFORMATION IS SHARED

4.1 With other users
Known4 is a collaboration platform, so some information is visible to others by design:

•  Your profile (name, title, role, profile picture, company, education, experience, skills, certifications, and industry codes) is visible to other signed-in Known4 users, who can find you by searching.
•  Your company can see that you've asked to join it. Its administrators can approve or decline your request, see its members, and remove members.
•  Job participants can see the job details, the messages, files, and polls shared in that job's conversations, and the read status of messages.
•  Companies you exchange RFPs, bids, proposals, or awards with can see the materials shared in those workflows.
•  A company that sponsors your subscription can see your sponsorship status and plan.

Please think carefully before sharing anything sensitive in messages or files: other participants can see it, save it, or forward it.

4.2 With service providers
We use trusted vendors who process information on our behalf, under contracts that limit their use of it to providing services to us:

•  Amazon Web Services (AWS): Hosting, databases, file and media storage, message storage, and transactional email
•  Google Firebase Cloud Messaging: Delivering push notifications
•  Apple (App Store) and Google (Google Play): Processing and verifying in-app subscription purchases
•  Stripe: Processing web and company-sponsored subscription payments
•  Dropbox, Microsoft, Google (only if you connect them): Accessing files you choose to share from your cloud storage

4.3 For legal reasons and business transfers
We may disclose information if we believe in good faith that it's necessary to comply with a law, regulation, court order, or other legal process; to protect the rights, property, or safety of us, our users, or the public; or to detect and prevent fraud or security problems.

If we're involved in a merger, acquisition, financing, reorganization, or sale of assets, your information may be transferred as part of that transaction. If so, it will remain subject to the protections in this policy, and we will notify you of any material change in how it's handled.

4.4 With your consent
We share information in other ways only when you direct us to or give us your consent.


5. DATA RETENTION
We keep your information for as long as your account is active and as needed to provide the Service. When you delete your account, or ask us to delete it:

•  We delete or de-identify your account, profile, and related personal information within 30 days, except as described below.
•  Messages and files you shared in job conversations or bidding workflows may remain visible to the other participants they were shared with, because they form part of a shared business record, but they will no longer be linked to your profile.
•  Copies may remain in backups for a limited period (up to 90 days) until they are overwritten.
•  We may keep certain records longer when the law requires it (for example, payment and tax records) or when we need them to resolve disputes, prevent fraud, or enforce our agreements.

Password-reset codes expire automatically after a short time. File-viewing links we generate are temporary and expire within about an hour.


6. SECURITY
We use administrative, technical, and organizational measures designed to protect your information. Among them:

•  Passwords are stored only as one-way hashes.
•  Authorization tokens for connected cloud-storage accounts are encrypted at rest.
•  Uploaded media and documents are kept in private storage and served only through short-lived, access-checked links.
•  Access to company and job data is limited to users who are authorized for that company or job.

No method of transmission or storage is completely secure, and we cannot guarantee absolute security. If we learn of a breach that affects your personal information, we will notify you and the relevant authorities as the law requires.

You are responsible for keeping your password confidential and for activity under your account. Contact us immediately if you suspect unauthorized access.


7. YOUR CHOICES AND RIGHTS

7.1 Choices available to everyone
•  Access and update: You can view and edit most of your profile and company information directly in the app.
•  Delete your account: Email us at jabberwarellc@gmail.com from the address associated with your account. See Section 5 for what happens next.
•  Notifications: You can turn off push notifications in your device or browser settings.
•  Device permissions: You can revoke camera, microphone, and photo-library access in your device settings.
•  Cloud storage: You can disconnect a connected Dropbox, OneDrive, or Google Drive account in the app at any time. You can also revoke access from that provider's account settings.
•  Subscriptions: Manage or cancel App Store subscriptions in your Apple ID settings and Google Play subscriptions in the Google Play app. Manage web subscriptions by contacting us. We cannot cancel an Apple or Google subscription on your behalf.

7.2 Additional rights depending on where you live
Depending on your location, including if you live in the European Economic Area, the United Kingdom, Switzerland, California, or another U.S. state with a comprehensive privacy law, you may have the right to:

•  know what personal information we hold about you and get a copy of it, including in a portable format;
•  correct inaccurate information;
•  delete your information;
•  object to or restrict certain processing;
•  withdraw consent where we rely on consent; and
•  opt out of the "sale" or "sharing" of personal information, or of targeted advertising. We do not do either.

To exercise any of these rights, email jabberwarellc@gmail.com. We will verify your request, usually by confirming it from the email address on your account, and respond within the time the law requires (generally 30 to 45 days). You may use an authorized agent where your law permits. We will not discriminate against you for exercising your rights. If we decline your request, you may appeal by replying to our decision. If you are in the EEA, the UK, or Switzerland, you also have the right to lodge a complaint with your local data protection authority.

California notice. In the past 12 months we have collected these categories of personal information: identifiers (name, email, phone, account and device identifiers); professional or employment information (title, role, company, experience, certifications); education information; commercial information (subscription records); audio and visual information (photos, videos, and voice messages you share); internet or network activity (presence, read status, and technical logs); and sensitive personal information limited to account login credentials. We collect these from the sources and for the purposes described in Sections 2 and 3, and disclose them to the recipients described in Section 4. We do not sell or share personal information, and we use sensitive personal information only as permitted by law to provide the Service.


8. INTERNATIONAL DATA TRANSFERS
We are based in the United States, and we store and process information in the United States. If you use the Service from outside the U.S., your information will be transferred to, stored in, and processed in the U.S., where data-protection laws may differ from those in your country. Where the law requires it, we rely on appropriate safeguards for these transfers, such as Standard Contractual Clauses.


9. CHILDREN'S PRIVACY
The Service is a professional tool intended for adults. It is not directed to children, and you must be at least 18 years old to create an account. We do not knowingly collect personal information from anyone under 18. If you believe a child has given us personal information, contact us at jabberwarellc@gmail.com and we will delete it.


10. THIRD-PARTY LINKS AND SERVICES
The Service may link to, or let you connect with, third-party services (such as cloud-storage providers, the app stores, or websites shared in chat). Their own privacy policies govern what they do with your information, and we are not responsible for their practices.


11. CHANGES TO THIS POLICY
We may update this Privacy Policy from time to time. When we do, we will change the "Last updated" date at the top. If the changes are material, we will give you additional notice, for example in the app or by email, before they take effect. If you keep using the Service after an update takes effect, the updated policy applies.
