This section will cover topics related to creating and managing your Knack account.
Creating an Account
In order to create your online database or web application you will first need to create a Knack account.
Visit our signup page and complete the account registration form here.

You will be asked to provide the following:
- Full name
- Valid email address
- Password: must be at least 6 characters.
- Account: a short name to use for your Knack URL where you can access your Knack apps.
- App Name: the name of the first app you want to build.
Once the signup form is submitted your Knack account will be created with a single blank app with the App Name you provided.
Free Trial
Knack offers a 14-day free trial period for you to explore and become familiar with the Knack online database platform. No credit card is required during this trial period.
Limitations during the trial
While the free trial offers a wide range of features for you to explore there are a few limitations.
All Starter Plan features are included during the trial unless otherwise noted below:
- Shared Builders - unavailable during the trial.
- Maps & Geo-Location - available during the trial but require a Pro plan or above to continue using.
- E-Commerce - available in test mode only.
- Scheduled Tasks - unavailable during the trial.
- Record History - unavailable during the trial.
- IP Blocking - unavailable during the trial.
- SSO - unavailable during the trial.
- Import Size Limits - limited to 10,000 records across all objects and apps. Additionally, your CSV cannot be any larger than 250 MB.
- API Increase Requests - unavailable during the trial. Trials include a daily limit of 1,000 API requests.
Purchasing a Plan
Upon the completion of the trial you will need to purchase a plan in order to continue to use your database.
To upgrade to a monthly or annual subscription plan you can visit the billing tab in your dashboard:
You will need to have a valid credit card to complete a plan upgrade. The following credit cards are accepted:
- Visa
- MasterCard
- American Express
- JCB
- Discover
- Diners Club
Your credit card will be charged at the end of the trial period and will be charged monthly/annually going forward.
Terms of Use
Knack has a detailed outline of the Terms of Use, however, there are some general questions we are often asked.
Can I sell apps that I create with Knack?
Absolutely. Many customers create custom apps for their clients or charge users to access the apps they build.
How do I cancel my account?
In your account dashboard you can use the "Delete Account" option which will close and completely remove your account. This cannot be undone.
Can I place my account on hold?
There is an option to freeze or pause your account one time annually at a deeply reduced monthly rate. You will not have access to your apps while accounts are "frozen."
Can I pay with a check?
You may pay with a check if you intend to purchase any Annual Corporate or Enterprise subscription. A request must be made and an invoice will be issued prior to the account becoming active.
How do I copy my app to another account?
You must make a formal request to transfer your app. The account holder must have an account in good standing and authorize the transfer.
You can find more details about copying apps here.
How do we gain access to a company account that a former employee created?
In order to gain access to a company account you must first attempt a password reset using the company email address.
If this is not feasible, you must provide the last 4 digits of credit card on file, the expiration date, and the security code to verify your company is the account owner.
Data Retention, Backups and Restore Options
Knack apps and data are backed up on a regular basis. These backups can be used to restore accidentally deleted objects, records, fields when needed.
Data & App Structure Retention Policies
Data
A record version is taken upon record creation, update and deletion and can be used to restore your data back to a particular time and date, if needed. After the retention period has lapsed, the previous data will be deleted. The last version of your record is stored regardless of the retention policy. Record versions are retained based on plan:
- Trial: 2 weeks
- Starter: 2 weeks
- Pro: 1 months
- Corporate: 2 months
- Plus: 3 months
- Enterprise: 3 months
- HIPAA: 3 months
As an example, on a Starter plan, a version history taken at 3:00 PM on Wednesday will no longer be available after 3:01 PM 14 days later.
App Structure
Restoring your app structure works a bit different, since versions aren’t taken every time you make a change. Instead, your app structure is backed up every 12 hours at 7AM and 7PM GMT.
Restores
Upon request, database records and/or app structure restoration can be fulfilled provided the record history or schema backup is still available, based on the retention policies as outlined above. Restoring records and apps normally take 1-3 hours of manual work, however, the processing time to complete the full restore can take longer than that.
Pricing
The fee to restore database records and/or application structure is $100/hr. for accounts on the Starter and Pro Plans. Restoration is included for Corporate and Plus Plans. Restoring is not an option during a trial.
Restoration Process
- Contact support@knack.com via email or login to the Knack help desk to make a request.
- Customer Support will confirm your request and outline next steps in the restoration process.
- Authorization will be requested to charge your Knack account $100 for the first hour (there is a one hour minimum charge).
- Once payment is successful, the restoration process will begin.
- You will be alerted when the process has completed and the balance due will be processed on your account. You are only charged for the time to prepare the restore, not for the time the system must process the restore.
- Confirm the state of your restore.
