Touchscreen Windows PCs $1.99 / Year
NEW • LIVE COLLABORATION, NO INTERNET NEEDED 7-DAY FREE TRIAL • $1.99 / YEAR

Draw with whoever, whenever.

Share your board with up to 10 people nearby and watch every stroke appear on everyone’s screen as it’s drawn. It runs fully local: your PCs connect directly over Wi-Fi or Bluetooth, so it works without internet, on campus Wi-Fi, and anywhere else, with nothing going through the cloud.

Every feature included • Cancel anytime

THE HEADLINE FEATURE • LIVE COLLABORATION OVER WI-FI & BLUETOOTH

Draw Together, Live, Right Where You Are

Tap Share in the top-right corner, host your board, choose how many people can join (up to 10), and give your friends, classmates, or teammates the 8-digit code. They tap Join a board on their own touchscreen PC and type it in (no list of boards, just the code), your board opens for them, and you’re all drawing on the same board at the same time.

  • See each other draw, live. Every stroke shows up on everyone’s screen as it’s being drawn, and moving pointers and objects glide smoothly, each person with their own name and colour.
  • Up to 10 people at once. The host picks how many can join, from a quick one-on-one to a whole study group.
  • No cloud, no accounts to link. The PCs talk directly, encrypted, over your Wi-Fi or Bluetooth. Nothing goes through the internet or our servers.
  • Works on campus Wi-Fi too. If your network won’t let PCs see each other (like eduroam), Slatisfy switches to Bluetooth by itself, and reconnects if the signal drops.
  • No bumping into each other. What you’ve selected is locked for everyone else, with your name on it, and Ctrl+Z only undoes your own work.
  • Saved by the host, copies if you like. The sketchpad stays on the host’s PC, and guests can tap Save a copy to keep it (the host can switch that off).

Everyone needs Slatisfy, plus the same Wi-Fi network or Bluetooth within about 10 m of the host. Included in the $1.99 / year plan.

YOU SAM'S PC You Wi-Fi or Bluetooth • PC to PC • nothing through the cloud
NO PEN? NO PROBLEM • SMOOTH TRACKPAD & FINGER DRAWING

Draw Smoothly With Your Trackpad or Your Finger

Most whiteboard apps assume you own a stylus. Slatisfy doesn’t. Turn on Smooth trackpad and just hold Ctrl and glide your finger on the trackpad: it draws, no clicking or dragging needed. On a touchscreen, turn on Finger drawing and your finger draws just like a pen.

  • Hold Ctrl, glide, draw. Hovering with Ctrl held draws, erases or lassoes with whatever tool you’ve picked. Add Shift to erase for a moment, and let go of Ctrl to finish.
  • Silky zoom on any trackpad. Pinch to zoom glides smoothly instead of jumping in steps, and two-finger scrolling pans the board.
  • Your finger is the pen. With Finger drawing on, one finger draws and two fingers still zoom and pan, so you never have to switch modes.
  • Tap two fingers to undo. It undoes instantly, and a Redo button pops up right above your fingers in case you went one step too far.

Both are one switch in Settings. Works on any Windows precision trackpad and any touchscreen.

Ctrl Ctrl TRACKPAD FINGER Hold Ctrl and glide • or just use your finger
FOR CLASS & HOMEWORK • MATH MODE

Real Math Symbols, One Tap Away

Switch on Math mode and a Math button appears next to Shapes, full of crisp symbols you’d never want to draw by hand: integrals, sums, derivatives, limits, roots, Greek letters, and logic.

  • Symbols behave like shapes. Drop them in, then scale, recolor, rotate and group them with your handwriting.
  • PDFs that never cut an equation in half. Export your notes to US Letter pages and the page breaks land between problems, not through them.

Turn it on in Settings › Math mode.

LIVING THEMES & SEAMLESS TRANSITIONS

Animated Worlds That Smoothly Fade In & Out

Choose between clean graph paper, ruled lines, or gently animated worlds like Underwater, Forest, and Space. Switching between themes or toggling between Light Mode and Dark Mode seamlessly cross-fades the background and every drawing's colors without any harsh flash.

☾ SEAMLESS LIGHT & DARK MODE FADE

Smooth Cross-Fade Between Light Mode and Dark Mode

Toggling between Light Mode and Dark Mode in Slatisfy never hits your eyes with a sudden, jarring flash. Instead, the entire board background, toolbar panels, and every single ink stroke and drawing on your canvas smoothly cross-fade together from light to dark.

PRIVACY & DATA DISCLOSURE

Privacy Policy

Privacy Policy for Slatisfy

Published by Maddening Games LLC • Effective Date: October 21, 2026 • Last Updated: October 25, 2026

Plain-English Summary: Slatisfy only collects two things: (1) feedback you choose to send through the in-app form, which includes your Google email address so we can reply, and any sketchboard you choose to attach to it, and (2) automatic crash reports if the app crashes, which never include your email address or Google account information. Your boards, drawings, and settings stay on your computer. If you choose Save to Google Drive or turn on Google Drive sync, your files go straight from your computer to your own Google Drive; we never see them, and Slatisfy can only see the files it saved there itself. If you use live sharing, your board goes straight to the other computer over your Wi-Fi or Bluetooth, never through us. Your subscription is handled by the Microsoft Store, so we never see your payment details. We never sell your data.
What we DON'T do
  • Sell or rent your data
  • Show ads or use your data for advertising
  • Receive your drawings or boards, unless you attach one to feedback yourself
  • Access your Gmail, Calendar, Contacts, or any Drive file Slatisfy didn't save
  • Track what you do inside the app
  • Use analytics, ad trackers, or cookies on our website
  • Attach your email to crash reports
  • See or store your payment details

1. Google Sign-In & the Google Data We Access

Slatisfy offers Google Sign-In so you can sign into your account inside the app. Signing in is optional: you can choose Continue without Google and use every feature except sending feedback, which needs your Google email address so we can reply, and saving to Google Drive. At sign-in it requests only basic access (the openid, email, and profile scopes). Only if you choose Save to Google Drive does it ask, separately, for the limited drive.file permission described in section 3. It does not access your Gmail, Calendar, Contacts, or any other Google service. Your signed-in session and Google profile information (your name, email address, and profile picture, which Slatisfy downloads from Google to show in the account button and keeps a copy of on your computer) are stored locally on your own computer and are not uploaded to our servers. Signing in does not upload your drawings. The only Google user data we ever receive is your email address, and only when you choose to send us feedback. We never receive anything from your Google Drive.

2. In-App Feedback (Email & Optional Sketchboard)

Whenever you voluntarily send feedback through Slatisfy's in-app feedback form, your message is collected along with your Google email address. We only use your email address to read your feedback, help solve your issue, and reply to you. We keep feedback only as long as needed to respond and improve Slatisfy, or until you ask us to delete it.

You can also choose to attach a sketchboard to your feedback (the board you have open, another of your boards, or a .slatisfy file). Nothing is attached unless you pick it. The attached board, including everything on it such as drawings, text, images, and videos, is sent with your message and stored in our feedback inbox and a private folder in our Google Drive, which only our team can open. We use it only to see and fix the problem you reported, never for anything else, and we delete it once we have dealt with your feedback, or sooner if you ask. Please don't attach a board with anything on it you don't want us to see.

3. Saving to Your Google Drive (Optional)

If you are signed in with Google, you can choose Save to Google Drive to save a picture, PDF, or backup of a board into your own Google Drive. The first time, Slatisfy explains what it needs and opens your browser so Google can ask your permission for the drive.file scope. This scope only lets Slatisfy create files and see or change the files and the "Slatisfy" folder that it created itself; it cannot see, read, change, or delete any other file in your Drive. Slatisfy uses this access only when you choose Save to Google Drive, or when you turn on Google Drive sync, and only to create the "Slatisfy" folder and save the files you chose there. The file goes directly from your computer to Google; it never passes through us, and we never receive, see, or store your Drive files or your Drive access. The permission is stored encrypted on your computer together with your sign-in. You can remove it at any time by signing out of Slatisfy, which revokes Slatisfy's access, or from your Google Account Permissions. Files you saved stay in your Drive until you delete them.

Google Drive sync (optional, off until you turn it on). When Slatisfy opens it may ask whether you want to sync your boards; you can say yes, not now, or "Don't show again", and switch it on or off any time in Settings › More settings › General. While it is on, Slatisfy copies each of your boards (everything on them, including pictures and videos you added) into a "Slatisfy / Synced boards" folder in your own Google Drive, downloads boards you made on your other PCs, and keeps them in step: when you change, rename or delete a board on one PC, the same happens on the others, and a deleted board goes to your Drive's trash, where you can recover it. This happens directly between your computer and Google; we never receive, see, or store your boards. Boards opened from your Downloads folder are not synced. Turning sync off stops it; boards already in your Drive stay there until you delete them.

4. Crash Reports (No Email Attached)

If Slatisfy encounters an unexpected error or crash, a crash report is sent to us so we can diagnose and fix the bug. Crash reports never include your email address, name, or Google account information. Like most crash reports, they contain technical details such as the app version, operating system, and error details, and the service that receives them may also see your IP address. We use them only to find and fix bugs and keep them only as long as needed for that.

5. Subscription & the Microsoft Store

Slatisfy is sold as a subscription through the Microsoft Store. Microsoft processes your purchase and payment, and its handling of that information is covered by the Microsoft Privacy Statement. We never receive your card number or other payment details. To check whether your subscription is active, Slatisfy asks the Microsoft Store on your computer for its licence status, and the Store keeps a copy so the check also works offline. Microsoft provides us with sales reports, which may include details such as the country and date of a purchase. If you redeem a developer code, it is stored encrypted on your computer only and is never sent to us.

6. Live Sharing over Wi-Fi & Bluetooth

When you host a board, Slatisfy does not announce it or list it anywhere, and your name and the board's name are never broadcast. Your screen shows an 8-digit code, and joining takes only that code. When someone types the code, their computer sends a short request on the local network (Wi-Fi or Ethernet) containing only a one-byte fingerprint derived from the code (not the code itself, and no names). Only a computer hosting a board whose code has that fingerprint answers, and it answers only the computer that asked, with a random session ID and a network port. The joining computer then connects and sends the full code; a wrong code is refused, and nobody is locked out, so other people and other hosts nearby are unaffected. Once connected, the board's contents (strokes, shapes, text, images, and any video files added to the board, which are saved in each participant's Slatisfy media folder), your display name, your pointer position, and what you are drawing are sent directly between the computers over your local network. If the board can't be found on the network (some school and work networks block that), Slatisfy uses Bluetooth instead: the joining computer sends a small Bluetooth signal that nearby devices can see, containing that computer's Bluetooth address, a random session ID, and the same one-byte code fingerprint (no names), and a nearby host whose code matches connects to it. The same board data is then sent directly between the two computers over Bluetooth. Windows may ask to pair the two computers the first time. When several people join, the host's computer passes each person's changes, pointer, and selection on to the others, again only between those computers. Nothing goes over the internet or through our servers, and we never receive, see, or store any of it. Everything sent between the computers is encrypted with a fresh key for each connection, so other devices on the same network can't read it. The board is saved on the host's computer. Guests can save their own copy of it if the host allows it (allowed unless the host turns it off), and in any case can see everything on it while connected and could capture it, for example with a screenshot. Whatever each person has selected is shared too, so the other person can see what is being worked on. Windows may ask you to allow Slatisfy through the firewall the first time you host, and you can turn Bluetooth off for your computer at any time in Windows Settings. Sharing stops when you choose Stop sharing or leave the board.

7. Sharing & Service Providers

We never sell your data, and we never use it for advertising. We do not share your Google user data with anyone except (a) service providers that receive and store feedback, attached sketchboards, and crash reports on our behalf, who may only process that data for us and not for their own purposes, and (b) when required by law. Only our team reads your feedback and email address, and only to respond to you.

8. No Other Data Collected

We do not collect, track, or use any other data for Slatisfy. All of your boards, sketches, images, and settings stay saved locally on your computer, and only leave it when you choose: to another computer nearby when you share live (over your network or Bluetooth), to your own Google Drive when you choose Save to Google Drive or turn on Google Drive sync, or to us when you attach a board to feedback. Our website does not use analytics, advertising trackers, or cookies. It does load its fonts from Google Fonts, so your browser connects to Google's servers when you visit.

9. Security, Children & Policy Changes

We use reasonable measures to protect the feedback and sketchboards we receive, though no method of storage or transmission is perfectly secure. Slatisfy is not directed to children under 13 and we do not knowingly collect their information. If we change how Slatisfy uses your data, including Google user data, we will update this policy and the date at the top before the change takes effect.

10. Google API Services User Data Policy & Deletion Requests

Slatisfy's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. You can sign out at any time inside Slatisfy's settings or revoke access from your Google Account Permissions. Data Slatisfy gets through the Google Drive permission is used only to save the files you choose to your own Drive, is never sent to us or anyone else, and is never used for advertising or to train AI models. If you have sent feedback and want your email, message, and any attached sketchboard deleted, email dev@maddeninggames.com and we will permanently delete it.

LICENSE & USAGE TERMS

Terms of Service

Terms of Service for Slatisfy

Published by Maddening Games LLC • Effective Date: October 21, 2026 • Last Updated: October 21, 2026

Plain-English Summary: Slatisfy is licensed to you, not sold. It needs an active subscription ($1.99 per year through the Microsoft Store, with a free trial first) and renews until you cancel in your Microsoft account. Use it on your own devices, your drawings stay yours, and you're responsible for what you share live with others. It is provided as-is, please don't misuse or resell it, and if something goes wrong our liability is limited to what you paid.

1. Agreement

By downloading, installing, signing in to, or using Slatisfy (the “App”), you agree to these Terms and to our Privacy Policy. If you do not agree, please do not use the App. You must be at least 13 years old, and if you are under the age of majority where you live, you need a parent or guardian's permission.

2. License

We grant you a personal, non-exclusive, non-transferable, revocable license to install and use the App on devices you own or control. Maddening Games LLC keeps all rights in the App, including its code, design, and trademarks. You may not copy, resell, sublicense, or distribute the App, reverse engineer it except where the law allows, remove its notices, or bypass its subscription, licensing, or payment.

3. Your Content

Your boards, sketches, images, and settings are saved locally on your computer and belong to you. We do not access, upload, or claim any rights to them. You are responsible for backing up your own work, since uninstalling the App or losing a device can mean losing what is stored on it.

4. Subscription, Billing & Cancellation

Using Slatisfy requires an active subscription, which costs $1.99 per year (or the equivalent price the Microsoft Store shows in your country, plus any applicable taxes). The subscription is sold and billed by the Microsoft Store under the Microsoft Store Terms of Sale, and we do not receive your card number. New subscribers may get a free trial (7 days, or as shown in the Microsoft Store when you subscribe). You are not charged if you cancel before the trial ends; otherwise it becomes the paid yearly subscription when the trial ends. It renews automatically each year until you cancel. You can cancel at any time in your Microsoft account, or email us and we will help. Cancelling stops future renewals, and you keep access through the end of the year you paid for. Without an active subscription the App cannot be used, but your boards stay saved on your computer. If we change the price, it applies only to future periods and we will tell you in advance.

5. Refunds

Refunds are handled by Microsoft under the Microsoft Store's refund policy, which you can request through your Microsoft account. You can also email us to ask about a refund, and we will review every request in good faith.

6. Updates & Availability

We aim to keep improving Slatisfy and to release updates regularly, but we do not guarantee any update schedule, specific features, or uninterrupted availability. We may add, change, or remove features, including to keep the App working with new versions of Windows, the Microsoft Store, or Google Sign-In.

7. Acceptable Use

Do not use the App or the in-app feedback form to break the law, send malware or abusive content, harass anyone, interfere with how the App or our systems work, or try to access anyone else's data or accounts.

8. Google Sign-In, Microsoft Store & Feedback

Signing in and Save to Google Drive are provided through Google and are also subject to Google's own terms; files you save to your Drive count toward your own Google storage. Purchases are also subject to Microsoft's own terms. We handle the data involved as described in our Privacy Policy. If you send us ideas or suggestions, we may use them freely without owing you anything, but your email address is still protected by our Privacy Policy.

9. Live Sharing

Live sharing connects your computer directly to another computer on the same local network, or nearby over Bluetooth, so you can work on the same board together. Both people need an active subscription. You are responsible for what you share and for making sure you have the right to share it, and shared content must follow these Terms. The shared sketchpad is saved on the host's computer, and guests can save their own copy unless the host turns that off. Anyone in the session can see everything on the board while connected and could capture it (for example with a screenshot), and we cannot recall or control what they do with it. Only share with people you trust, on networks you trust. Network and Bluetooth connections can drop or be slow, and live sharing is provided as-is, so changes made during a session may occasionally be lost or arrive out of order.

10. Developer Codes

We may give developer codes to testers, reviewers, or partners. A developer code is personal to the person we gave it to, may not be shared, sold, or published, and gives access only for as long as we allow. We may stop accepting or disable developer codes in future versions of the App. Using a developer code you were not given is a breach of these Terms.

11. Disclaimer of Warranties

THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not promise that the App will be error-free, uninterrupted, or that your content will never be lost. Some places do not allow these exclusions, and any consumer rights you have under your local law are not affected.

12. Limitation of Liability

TO THE MAXIMUM EXTENT THE LAW ALLOWS, MADDENING GAMES LLC IS NOT LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST DATA, PROFITS, OR GOODWILL. OUR TOTAL LIABILITY FOR ANY CLAIM RELATED TO THE APP IS LIMITED TO THE AMOUNT YOU PAID FOR SLATISFY IN THE 12 MONTHS BEFORE THE CLAIM.

13. Termination

You can stop using the App at any time by uninstalling it and cancelling your subscription in your Microsoft account. We may suspend or end your access if you seriously or repeatedly break these Terms. If we ever discontinue Slatisfy, we will give reasonable notice and refund any unused part of a period you have already paid for.

14. Governing Law & Disputes

These Terms are governed by the laws of the state in which Maddening Games LLC is organized, without regard to conflict-of-law rules. Before filing any claim, please email us so we can try to resolve it informally. If you live somewhere with mandatory consumer protections, those protections still apply to you.

15. Changes to These Terms & Contact

We may update these Terms from time to time. When we do, we will change the date at the top and, for material changes, tell you in the App or on this website. Continuing to use Slatisfy after a change means you accept the updated Terms. Questions? Email Maddening Games LLC at dev@maddeninggames.com.
