## What is CarbonData?

Please note: The ability to generate certificates can only be unlocked through a monthly subscription*

CarbonData is an app specially designed by sweeps for sweeps. It’s the digital version of the chimney-sweeping certificate given out to customers once a job has been completed.

With CarbonData, you can personalise your certificate with your company details, logo, signature and approved trade / association symbols in the ‘Settings’ section as soon as the app is installed (don’t worry, these can be changed later).

The app itself is very easy to use. When creating a certificate, simply search the Contacts section on your device and it will instantly complete the customers’ details for you. Or, if you prefer, you can enter their details manually.

CarbonData really does help make a sweep’s work less hassle. It allows you to document all aspects of the flue and appliance you have swept; list any faults using comment boxes and a robust traffic light system; whilst making it clearer for customers to understand all the relevant information and any issues found.

You can track the progression of the certificate with the navigation dots at the base of the screen and check each section as it appears on the certificate. A handy visual checklist at the end of the process quickly reveals any unfilled sections. Plus, certificates can still be issued even if one or more sections are incomplete. 

And there’s more.

Before issuing a certificate, sweeps can obtain the customer’s consent to the status of the site, permission for any future contact, and get the client’s signature. There’s even an option to indicate if the client wasn’t present at the time the job was done. 

The completed certificate can then be dated and supplied to the customer via the sweep’s email as a PDF file ready to send. Sweeps then have the option to attach more images to the email, so giving customers even more info. 

In the event of poor mobile reception or Wi-Fi being unavailable at the time of issue, the email will remain in the ‘Outbox’ until you get better reception or Wi-Fi comes back on. Once sent, a copy is stored in your ‘Sent’ items, so you’ll have a reliable backup or duplicate.

Certificates can be viewed, deleted, emailed or organised by date or name in the 'View Certificates’ section and data can be exported as a CSV format.

Finally, CarbonData does not store any information on the Cloud. Everything is stored on your device. So your personal database remains exactly that - personal.

Key benefits of CarbonData:

• Easy to use
• Environmentally-friendly
• Export database as a CSV file
• No need for cloud technology
• Designed for use in any country
• Create certificates wherever you are
• Issue certificates with device email
• Add accompanying photos with email
• Keep certificates organised

### 5/5 — Brilliant little app ...

*2023-04-24, version 1.4.2*

This is a brilliant little App for Chimney Sweeps!

### 4/5 — Good app

*2020-11-16, version 1.4.2*

I have been using CD since its release and through the subsequent large update. The changes made were great, such as capitalising names and postcodes. It’s speeds up the process of data input.

It’s a great app and love using it. 

One slight criticism is of the auto reminder option. When setting a reminder, for example 6 months time, it changes the validity of the certificate to 6 months as well. I would rather that the reminder is simply that. Set it to 11 months, they get a reminder then we can book in an appointment before 12 months are exceeded.

My concern is if an insurance company requires a certificate following a chimney fire etc, they will see an expiry, which is simply the reminder date and argue that the certificate is out of date, say between month 11 and 12.

### 3/5 — This is really for EU Chimney Sweeps

*2020-09-20*

It seems to ask for items that are not comparable to the US Market. We don’t have “ smoke control zones” in America. The app is not as customizable as it could be. I like to be able to create a field to make the inspection more to the areas we serve. 
Try to attach a T&C file. Forget it. 10$ a month is a bit much for the current version of this app.

### 5/5 — So simple!

*2019-10-13, version 1.0*

I’ve been looking for something to replace my paper certificates, this is brill, very slick and the traffic lights makes it so much easier to explain to the customer between what’s dangerous and what’s an advisory. Well done.

### 5/5 — This rocks!

*2019-10-13, version 1.0*

I’ve just discovered this, how long has it been out there?!! I’ve just started using it and it’s brilliant, there’s no fuss just exactly what I need when I need it.
