Maximum flexibility

With Fleksy keyboard SDKs, you can fully customize the look and feel of the keyboard. From the colors, fonts, sounds, and more! You get full control to make it a natural extension of your brand.

International reach

Fleksy has 82+ languages natively available, enabling instant reach to over 4 billion people worldwide. New languages are added regularly, increasing the capabilities of your most ambitious projects.

White-label ready

Fleksy owns ALL of its technology: source code, algorithms, autocorrection, next-word prediction, dictionaries, swipe, and more. Unlike other virtual keyboards that rely on 3rd parties or open-source, Fleksy has the power to modify and curate its technology to best fit your needs.

Highest level of privacy

Privacy is Fleksy’s number one commitment to its millions of users worldwide. No other keyboard on the market has built this level of data encryption and made it a priority to operate on user devices without ever sharing users’ personal data.




Does Fleksy collect data?

No, Fleksy NEVER receives ANY DATA from your SDK usage except for the number of licenses in use.

Can I test the SDK?

Yes, subscribe here or set up a brief call here. Our SDKs are free to try for 30 days.

What kind of data can we collect?

Since we (Fleksy) are in full control of our Intellectual Property (IP), we can customise any parameter that you might need. There are many different parameters for typing data in raw format.

How do we make our services or products available inside the keyboard?

Build a mini-app that connects to your API, and display whatever you want – directly in the top bar of the keyboard!

Fleksy’s Virtual Keyboard SDK provides all the framework to build your mini-app.

Does Fleksy use AOSP?

No, Fleksy owns 100% of its IP making it the most customizable keyboard on the market. We have no intention to use any external code.

What kind of programming engineer do we need to implement your Virtual Keyboard SDK?

An Android and/or iOS Engineer is all you need to complete the integration.

How big is the Virtual Keyboard SDK?

The Virtual Keyboard SDK is less than 32 mb. The Predictive Keyboard SDK is super lightweight.

Where does the data travel?

Data goes from Fleksy’s Virtual Keyboard SDK directly to the customer’s host App, locally on-device. Data generated by the user stays inside the user’s device and is stored locally on their device. It is up to the Fleksy Virtual Keyboard SDK customer (You) to decide how to handle the data. Fleksy NEVER receives ANY DATA from your SDK usage except for the number of licenses in use.

Can we create different views with the Virtual Keyboard SDK?

Yes, you can create any view you want.

You can change buttons and make them perform different actions.

Example: You can change the emoji button that’s next to the spacebar so it loads a webview of your products instead of showing emojis.
