For tax advisors & accounting firms

Confidential communication with your clients — leaving nothing behind.

COVANAN connects you and your clients directly, end-to-end encrypted. Your client joins with one click on a link — no app, no account. And nothing is ever stored on a server.

GDPR-minded · professional confidentiality preserved · servers in Germany

Email and WhatsApp are a liability for a tax firm

Standard email is unencrypted — every tax return, balance sheet or payroll statement sent that way can be read in transit. For a tax advisor that directly touches your duty of confidentiality and your obligations under the GDPR.

WhatsApp, in turn, sends contacts and metadata to a third party — hard to justify inside a regulated practice.

How COVANAN solves it

No central store, no data breach.

The connection runs directly between devices and the keys never leave yours. There is simply no central copy that could be hacked, subpoenaed or leaked.

Your client needs no app and no account.

They click your link and they are in the conversation. That removes the biggest obstacle to secure tools: the other side not playing along.

Encrypted document exchange.

Receipts, balance sheets and other records travel directly device-to-device, up to 500 MB per file (Spark Pro) — never through a server.

Why you can trust COVANAN

Security here is not a setting; it is the architecture. The servers are located in Germany, and no conversation, contact or connection data is ever stored.

Frequently asked questions

Is COVANAN GDPR-compliant?

Because no content, contacts or connection data are stored on our servers, no central data collection is created in the first place. For a definitive assessment of your specific situation, please confirm with your data protection officer.

Does my client need to install anything?

No. COVANAN runs in the browser. Your client opens your link and is in the conversation instantly.

What about record-retention duties?

COVANAN is built for the confidential conversation and exchange in the moment. Records you are required to retain stay in your practice software or DMS as usual — COVANAN does not replace them; it adds a secure communication channel.

Do I need an account?

You, as the firm, create a free account (just an email address). Your client does not.
