Free trial and purchase

Solidly includes a free 30-day trial that provides every feature of the application. No payment card is required to start the trial, and it ends automatically without any charge. After the trial, Solidly Standard keeps every feature available as a one-time, permanent purchase, not a subscription. The License Agreement sets out the terms of the license.

The direct download and the Mac App Store build handle the trial and the purchase separately. The direct download uses a Solidly account, and the Mac App Store build uses in-app purchases made with your Apple Account. A purchase made for one distribution does not unlock the other.

What the trial includes

The trial includes every feature described in this documentation, including editing, saving, compression, Photo Mode, Quick Look previews, and, in the direct download, the solidly command line tool. Solidly Standard includes the same features, together with every later version of Solidly at no additional cost.

When Solidly is locked

When a trial has ended and Solidly has not been bought, Solidly is locked on that Mac. The window shows a screen that explains why and offers a way to buy Solidly. While Solidly is locked:

• models cannot be opened, edited, saved, or exported
• Photo Mode cannot capture an image
• Quick Look previews are drawn by the macOS previewer instead of by Solidly
• the solidly command line tool reports that it is locked and exits without doing anything

Your files and settings are not changed. A model opened from the Finder while Solidly is locked opens once Solidly is unlocked.

The direct download

Signing in

The direct download requires a Solidly account. When Solidly opens on a Mac with no account signed in, the window shows Sign In and Create Account. Both continue in the browser on app.solidly.dev, and Solidly continues once the browser returns to it. An account costs nothing to create.

While Solidly confirms the account with app.solidly.dev, the window shows Checking your account.

Starting the trial

The first time an account signs in on a Mac, Solidly runs a short setup covering crash reports, usage data, file types, Quick Look, and the command line tool. The last step describes the trial and shows the date on which it will end. Press Accept to start the trial.

Each account has one free trial, and each Mac can take part in one free trial. A trial that has started on one Mac can also be used on a second Mac signed in to the same account. On the second Mac the setup ends on Add this Mac to your free trial, and the trial keeps its original end date.

If a Mac has already taken part in the trial of a different account, Solidly shows This Mac has already had a free trial. To use Solidly on that Mac, buy it with the account that is signed in, or log out and sign in with the account that started the trial. Creating a new account, deleting an account, or reinstalling Solidly does not make a Mac eligible for another trial.

The remaining time is shown in Settings ▸ Account and in the Your Macs section of the account page on app.solidly.dev.

When the trial ends

Solidly locks on the date shown when the trial started. The window then shows Your free trial has ended, with Buy Solidly and Log Out. The trial ends on that date whether or not the Mac is connected to the internet.

Buying Solidly

Buy Solidly opens the purchase page on app.solidly.dev, where Solidly Standard is bought for the account that is signed in. Solidly can also be bought at any time during the trial with Buy in Settings ▸ Account. The payment is processed by Stripe, which issues the receipt. Purchases and Refunds describes the checkout, receipts, and refunds.

If Solidly is locked when you return to it after buying, it checks the account again at once and unlocks when the purchase is confirmed. While Solidly is locked, Settings ▸ Account also offers Check Again. A purchase made during the trial is confirmed at the next hourly check or the next time Solidly opens, and from then on the trial's end date does not apply.

Using Solidly on two Macs

A trial or a purchase can be used on up to two Macs signed in to the same account. Signing in on a third Mac shows Solidly is already in use on 2 Macs, with Manage Macs, which opens the account page.

The Your Macs section of the account page lists each Mac, with the date it was added and the date it was last used. Removing a Mac stops Solidly from working on it and makes its place available to another Mac. One Mac can be removed every 30 days, and the account page shows the date on which the next removal becomes available. Removing a Mac does not make it eligible for another free trial.

Connecting to the internet

Solidly confirms the account with app.solidly.dev when it opens, every hour while it is open, and when the Mac wakes from sleep. Each confirmation allows Solidly to be used without an internet connection for up to seven days. If Solidly has not been able to confirm the account for seven days, the window shows Solidly can't reach your account until the Mac is connected to the internet and Try Again succeeds.

The command line tool and the Quick Look extension rely on the confirmation recorded by the application and do not connect to app.solidly.dev themselves. If the command line tool reports that the Mac has not checked in, or Quick Look previews are drawn by macOS instead of by Solidly, open Solidly once while the Mac is connected to the internet.

Signing out

Settings ▸ Account ▸ Sign Out signs the account out of this Mac, and the locked screens offer Log Out for the same purpose. Solidly is locked until an account signs in again, and the next account to sign in goes through the setup again. Signing out does not remove the Mac from the account. Use the account page to remove it.

Deleting an account

Settings ▸ Account ▸ Delete Account opens app.solidly.dev, where the deletion is confirmed. The account is deleted seven days after it is confirmed, and signing in before then cancels the deletion. Until then, Solidly shows Your account is scheduled for deletion, with Reactivate and Log Out.

Once an account is deleted, its purchase cannot be restored. The Privacy Policy describes what is deleted and what is kept.

The Mac App Store build

The Mac App Store build does not use a Solidly account and has no sign-in. The free trial and Solidly Standard are in-app purchases made with your Apple Account.

Starting the trial

The first time Solidly opens, the setup ends on Start your 30-day free trial. Before the trial can be started, the screen shows the date on which it will end, what stops working when it ends, and the price of Solidly Standard in your App Store region. Start Free Trial opens the App Store purchase sheet for the 30-Day Trial, which costs nothing.

The trial lasts 30 days from the date the App Store records for that purchase. It belongs to the Apple Account, so reinstalling Solidly, opening it on another Mac that uses the same Apple Account, or obtaining the trial again does not restart it. The trial is not available through Family Sharing.

The remaining time is shown in Settings ▸ Purchase.

When the trial ends

The window shows Your free trial has ended, with a button that buys Solidly at the price shown and Restore Purchases.

Buying and restoring purchases

Solidly Standard can be bought from the trial-ended screen, or at any time from Settings ▸ Purchase. The purchase is made through the App Store and belongs to your Apple Account.

Restore Purchases asks the App Store to deliver the purchases made with your Apple Account again. It appears on the trial screen, on the trial-ended screen, and in Settings ▸ Purchase. Use it if Solidly does not recognize a trial or a purchase you have already made, for example on a newly set up Mac.

Apple decides refunds for purchases made in the Mac App Store. See Purchases and Refunds.
