Office SMS Sync — Privacy Policy

Last updated: 27 July 2026

Office SMS Sync is an internal tool provided by the accounting firm that operates flow.izid.io ("the Firm") to its own authorized employees. It lets an employee forward selected incoming SMS messages from their work phone into the Firm's internal system, so business messages are handled alongside the Firm's other customer conversations. It is not intended for the general public.

The core guarantee: the app filters on the device, before anything is transmitted. A message that does not match the rules the employee configured is never stored by the app and never sent anywhere — it is only counted. Until the employee has read the in-app consent screen and explicitly chosen a rule, the app transfers nothing at all.

How the filter works

Setting	What is transferred
Off (the default)	Nothing. This is the state of a freshly installed app.
All messages	Every incoming SMS.
Only from specific numbers	Only messages whose sender matches a number the employee listed.
Only containing a word	Only messages whose text contains a term the employee listed.

Setting

What is transferred

Off (the default)

Nothing. This is the state of a freshly installed app.

All messages

Every incoming SMS.

Only from specific numbers

Only messages whose sender matches a number the employee listed.

Only containing a word

Only messages whose text contains a term the employee listed.

The rules are evaluated on the phone. Non-matching messages never leave the device. The rules are also stored on the Firm's server so they survive reinstalling the app, and are re-applied there when a message is received, so that a message the employee's current rules exclude cannot be accepted.

What is collected (only for messages that match the rules)

Data	Why
The sender's phone number or sender ID	To attach the message to the right customer conversation.
The message text	It is the content being forwarded; this is the purpose of the app.
The time the message was received	To place it correctly in the conversation.
A device identifier generated by the app, and the app version	To group uploads from one phone and to diagnose sync problems.
Your sign-in token	Held in the phone's encrypted storage to authenticate requests to the Firm's server.

Data

Why

The sender's phone number or sender ID

To attach the message to the right customer conversation.

The message text

It is the content being forwarded; this is the purpose of the app.

The time the message was received

To place it correctly in the conversation.

A device identifier generated by the app, and the app version

To group uploads from one phone and to diagnose sync problems.

Your sign-in token

Held in the phone's encrypted storage to authenticate requests to the Firm's server.

What we do NOT do

Who can see a transferred message: a message that matches the rules appears in the Firm's shared internal message centre, where the employee's colleagues and managers can read it, in the same way they can read the Firm's other customer conversations. The app's own private “my messages” list is visible only to the employee unless they share an individual message, and every such reveal is recorded. This difference is stated on the consent screen and again in the app's settings, so it is understood before any rule is chosen.

Why the app requests its permissions

Permission	Reason
`RECEIVE_SMS`	To see an incoming SMS at the moment it arrives, so a matching business message can be forwarded promptly.
`READ_SMS`	To re-read recent messages from the system inbox during the periodic catch-up, which recovers messages missed while the device was offline or restarting, and reassembles multi-part messages.
`INTERNET`, `ACCESS_NETWORK_STATE`	To upload matching messages to the Firm's server.
`FOREGROUND_SERVICE`, `FOREGROUND_SERVICE_DATA_SYNC`, `WAKE_LOCK`	To keep the upload queue alive so a message is not lost when the device sleeps.
`RECEIVE_BOOT_COMPLETED`	To resume syncing after the phone restarts.
`POST_NOTIFICATIONS`	Android 13+ requires this to display the sync status notification.

Where data goes

All data is sent only to the Firm's own server at https://flow.izid.io, over HTTPS. No other destination receives any data from this app.

Retention and deletion

Transferred messages are retained in the Firm's system as part of its business records. An employee can stop syncing at any time from the app's settings, either by pausing it or by withdrawing consent entirely; withdrawing consent also resets the rules, so syncing cannot silently resume later. To request deletion of messages already transferred, or deletion of your account, contact the Firm at the address below and the request will be actioned within 30 days.
