Kayus Systems
Privacy Policy
This policy explains how Kayus Systems handles information submitted through the Kayus Systems website. It applies to the public assessment, customer results, solution plans, payments, service emails and the ReviewFlow product in this version of the platform.
KAYUS SYSTEMS is a registered Nigerian Business Name (BN 9759219), operated as a sole proprietorship. Its registered address is 20, Yisa Omotunde St, Ketu, Lagos State, Nigeria; its registered email is [email protected].
Information we collect
We collect the information you choose to provide, including:
- your name, email address, phone or WhatsApp number, country and optional business or brand name;
- your answers about the repetitive work, tools, time involved, desired result and work you want to keep under human control;
- Kayus review notes, assessments, solution plans, quotes, project status and service communication records;
- payment status, amount, currency, reference and limited gateway information returned by the secure third-party payment provider currently configured for the service. Kayus Systems does not collect or store your full card details.
- participating ReviewFlow business configuration, customer contact details supplied for legitimate feedback requests, feedback ratings, optional private comments, message status and service-recovery records;
- WhatsApp Business account, sender and messaging identifiers needed to configure or operate approved messaging integrations.
How we use information
We use this information to:
- understand and assess the problem you submit;
- decide what may be simplified or automated and what should remain under human control;
- prepare and deliver assessments, solution plans and quotes;
- verify payments and provide the agreed service;
- operate ReviewFlow feedback requests, private feedback collection, review links and service-recovery workflows;
- configure and operate approved WhatsApp Business messaging connections for participating businesses;
- send essential service messages and respond to questions;
- protect the platform and maintain accurate business records.
ReviewFlow and participating businesses
A participating business may provide customer contact information to ReviewFlow so it can request feedback on that business's behalf. The participating business is responsible for ensuring it has the permission or other lawful basis required to contact those customers. ReviewFlow is not intended for passwords, payment-card details, medical records or other unnecessary sensitive information.
Feedback submitted through ReviewFlow is private to the participating business unless the customer separately chooses to use the public Google review opportunity. ReviewFlow does not make private feedback public automatically.
WhatsApp, Meta and messaging providers
ReviewFlow is designed to use Meta's WhatsApp Business Platform through an approved service-provider integration. Information needed for account setup, message delivery, status updates and troubleshooting may therefore be processed by Meta, WhatsApp and the configured provider under their respective terms and privacy practices.
AI-assisted review
Kayus may send relevant questionnaire information to a configured AI provider to prepare an internal draft analysis. AI output is not sent to you as a final recommendation without human review. Do not submit passwords, payment-card details or information you do not have permission to share.
Service providers
Kayus uses service providers only where needed to operate this platform. These may include Railway for hosting and PostgreSQL data storage, the configured AI provider for draft analysis, Resend for transactional email and a secure third-party provider for hosted payment processing. Payment provider details may vary based on the provider currently configured for the service. Each provider handles information under its own terms and privacy practices.
Storage, access and retention
Access to customer records is restricted to approved Kayus administrators. Private customer pages use unguessable links; anyone with a valid link may be able to view that page, so keep it private. We retain information for as long as reasonably needed to assess the request, deliver the service, maintain business and payment records, resolve disputes and protect the platform. We may delete or anonymise information when it is no longer needed.
Your choices and data deletion
You may ask Kayus to explain, correct or delete personal information we hold, subject to records we reasonably need to keep for payments, security, legal obligations or an active service. For privacy or data enquiries, email [email protected].
Detailed deletion instructions are available on our Data Deletion page.
Security and limits
Kayus uses practical access controls, validation and secure connections, but no online service can promise absolute security. Please submit only information needed for the assessment.
Changes to this policy
We may update this policy as the service changes. The effective date above identifies the current version.
