You're trusting HisabOne with tax documents and filings. Here's exactly how we protect them — described honestly, with no invented badges — together with our full Privacy Policy, Terms of Use and AI disclaimer.
Every request is served over TLS, and your files and records are encrypted at rest in managed cloud storage.
Every record is scoped to your account in the database itself. Businesses, accountants and team members see only what their role permits — not just hidden in the UI.
Uploads live in a private bucket, never public. When you share a document we generate a time-limited signed link — so access is deliberate and revocable.
Document reading runs on Anthropic's Claude, used only to extract the dates you asked for from your file — never to train models.
Every document access, every signature and every change is logged and timestamped, so there's always a clear record of who did what, and when.
Export your records anytime, and delete your account and its data whenever you choose.
HisabOne runs on a small set of trusted infrastructure providers. We keep this list current so you always know who processes your data:
HisabOne is in private preview. We follow security best practices — encryption, least-privilege access and full audit logging — but we don't yet hold formal certifications such as ISO 27001 or SOC 2. Those are on our roadmap, and we'd rather tell you plainly than display a badge we haven't earned.
AI can make mistakes. HisabOne includes artificial-intelligence features: automatic document and date reading, invoice OCR and expense auto-categorisation, the AI Assist chat, the penalty-exposure checker, and the VAT and Corporate Tax calculators and draft returns. You acknowledge and agree that:

HisabOne (“we”, “us”) provides a UAE tax & compliance workspace connecting businesses and their accountants, available at hisabone.ae. For any privacy question or request, contact us at info@hisabone.ae.
When you create an account we collect your name or company name, email address and password (stored only as a secure cryptographic hash by our authentication provider). While you use HisabOne we store the compliance data you choose to put in it: company profile details, document requests, deadlines, reminders, reports, draft returns, messages, and the company documents you upload to your vault.
Under UAE Federal Decree-Law No. 45 of 2021 (the PDPL), consent is the primary lawful basis for processing personal data. By creating a HisabOne account and using its features you consent to the processing described in this policy. You may withdraw consent at any time by closing your account, after which your data is deleted as described below.
Your data is used solely to provide the service — showing your own workspace, sharing records you explicitly share with your linked accountant or clients, and sending the emails you ask us to send (such as document requests and reminders). We do not sell personal data, and we do not use your data for advertising.
Some features send data to an AI model (Anthropic's Claude) to work: automatic document and date reading, invoice OCR and expense categorisation, and the AI Assist chat (which receives a short summary of your workspace so its answers are specific to you). This data is processed only to provide the feature and is not used to train AI models. AI output can contain mistakes — see the AI accuracy disclaimer in our Terms of Use.
Your account and workspace data is stored with Supabase (managed PostgreSQL and encrypted file storage) in the EU — Frankfurt region. The website is served by Vercel's global network; AI requests are processed by Anthropic (United States); and email is delivered by Resend (United States). Because these providers operate outside the UAE, using HisabOne involves cross-border transfers of your data as contemplated by Articles 22–23 of the PDPL. We protect those transfers with TLS encryption in transit, encryption at rest, contractual data-processing terms with each provider, and by sending each provider only the minimum data its function needs. You consent to these transfers by using the service.
We keep your data while your account is active. Deleting your account removes your profile, workspace records and uploaded files from our systems; residual copies in encrypted backups expire on the backup provider's rotation schedule.
In line with the PDPL, you may request access to, correction of, or deletion of your personal data at any time, and you may object to or ask about any automated processing we perform, by emailing info@hisabone.ae. We respond to every request.
We use only the browser storage necessary to keep you signed in, plus privacy-friendly, cookie-less visit analytics (Vercel Web Analytics). We do not use advertising or third-party tracking cookies.
If this policy changes materially, we will note the new date at the top of this page. Questions? Email us.

HisabOne is a workspace that helps UAE businesses and their accountants organise tax and compliance work — registrations, filings, audits, documents and deadlines. HisabOne is a software tool: it does not provide tax, legal or audit advice, and it does not file returns with the Federal Tax Authority on your behalf. Decisions and filings remain the responsibility of you and your professional advisers.
You are responsible for the accuracy of the information you enter, for keeping your password confidential, and for ensuring you are authorised to upload the documents you store. One account per legal entity; accountants may manage multiple linked clients through the accountant portal.
Accounts start on the entry plan for their portal and stay there until you choose to move — nothing expires and no credit card is required to begin. Accounting firms carry up to 30 active clients free of charge, permanently. Moving to a higher plan takes effect immediately and is invoiced separately; prices exclude 5% VAT unless stated otherwise. You can change or reduce your plan at any time from Settings.
You retain all rights to the data and documents you upload. You grant us only the licence needed to store, process and display them to provide the service, as described in our Privacy Policy — including storage with EU-hosted infrastructure and AI processing by our providers. You may export your data and request deletion at any time.
AI can make mistakes. HisabOne includes artificial-intelligence features: automatic document and date reading, invoice OCR and expense auto-categorisation, the AI Assist chat, the penalty-exposure checker, and the VAT and Corporate Tax calculators and draft returns. You acknowledge and agree that:
If you spot a suspected AI error, please report it to info@hisabone.ae so we can investigate.
You agree not to misuse the service — including attempting to access other accounts' data, uploading unlawful content, or using the platform to send spam.
We work to keep HisabOne available and accurate, but the service is provided “as is” without warranties. To the maximum extent permitted by law, our liability is limited to the fees you paid in the twelve months before a claim. Nothing in these terms excludes liability that cannot be excluded under UAE law. Deadlines shown in HisabOne are aids, not guarantees — always verify statutory deadlines with the FTA or your adviser.
You may close your account at any time. We may suspend accounts that breach these terms. On closure, your data is deleted as described in the Privacy Policy.
These terms are governed by the laws of the United Arab Emirates. Contact: info@hisabone.ae.
A due-diligence request, a data-processing question, or a vulnerability to report — we'll respond.
