Preparing with Lantern

Lantern is an early alpha for private campaign preparation. Write ordinary pages, link characters and monsters, and duplicate notes you want to reuse for the next session.

Start with your next session

Sign in with a code sent to your email to open your campaign. Your first page starts blank. Add pages from Documents and arrange your notes however you like. Click the campaign name at the top of the sidebar to switch campaigns or create another one.

Find and reuse your notes

Search campaign (⌘/Ctrl K) finds page titles and text in your current campaign. Offline, it finds the titles of the pages on this device. Recent saved edits can take a few seconds to appear in text search. The current page’s local edits are marked “On this device”. Library and compendium searches are separate.

Choose Duplicate from a page’s Document actions menu to make an independent copy. You can clear completed checkboxes for the next session. Returning to a campaign opens your last accessible page; direct links still open the page you chose.

Export and recover

Export in a page’s Document actions menu downloads that page as Markdown or page data, including edits that have not reached the server yet.

Healthy saving stays quiet. If a save or upload fails, keep the page open and use its recovery controls. A local recovery download includes this browser’s available cached notes, images and title drafts, and reports gaps. It is not a complete server export. Don’t clear browser storage before recovering unsaved work.

Use Trash in the campaign menu to restore recently deleted pages, normally for 30 days, or to delete them forever sooner, which can’t be undone. To restore a whole campaign, open the campaign picker and choose Trash. Campaigns are permanently deleted after 30 days. Keep separate exports of important material. Contact me if these options do not help.

Current limitations

Lantern is a free alpha and beta, built and supported by one person. There is no live combat tracker, player view, sharing or complete offline download. Features can change, and bugs or interruptions can happen. Google sign-in is not currently available; use your email code.

Support & feedback

Email angus@withlantern.app. I read feedback and support requests myself. Replies may take a while. Please include what you were trying to do and what happened; never send a sign-in code.

Privacy

Last updated: 28 October 2026

Lantern is operated by Angus in Victoria, Australia. For privacy questions or requests, contact angus@withlantern.app.

Information collected

Lantern collects your email, account name, account and session identifiers, IP address and browser information to provide sign-in and account security. It stores the campaigns, notes, images and other content you add, including edits and recovery copies, to save, synchronise, search and recover your work. Uploaded images may contain metadata.

Feedback includes your message, category, optional reply address and any connection or window-size information you choose to attach. It is linked to your account and emailed to the operator. Your account email and private content are not automatically attached to that email. Direct emails include the sender details and attachments you provide.

Hosting services also collect request and error information to operate, secure and troubleshoot Lantern. Product activity measurement is currently disabled. Lantern does not sell personal information or use advertising or third-party behavioural analytics.

Service providers and disclosure

Cloudflare provides hosting, storage, backups and contact-email forwarding. Resend delivers sign-in and feedback emails. Google Gmail stores support correspondence. These providers process information internationally, including in the United States; Australian-only storage is not guaranteed.

Campaigns are private to your account, but are not end-to-end encrypted. The operator can access information when needed to run Lantern, provide support, investigate problems or comply with legal obligations. Information may also be disclosed where legally required or necessary to address abuse or protect users and the service.

Cookies and browser storage

Lantern uses a necessary sign-in cookie and browser storage for preferences, navigation, cached content and unsaved work. Private content may remain on your device after closing a tab. Signing out clears account caches in that browser after handling any unsaved-work warning. Downloads and copies on other devices remain under your control. Clearing browser storage before syncing can lose unsaved work.

Retention and deletion

Account and content information is kept while your account is active. Trashed pages and campaigns are recoverable for 30 days and then permanently deleted; you can also permanently delete trashed pages sooner from Trash, which cannot be undone. Removed text may remain in a page's sync history while the page exists. Uploaded images and files are kept while any of your campaigns shows them. Once none does, they are deleted after about seven days, and with your account.

Account deletion removes your account and campaign data. If deletion is interrupted, the account remains so you can retry. The hosting provider's point-in-time recovery history, used only to repair service failures, expires after approximately 30 days.

Stored feedback is removed on account deletion or request. Support emails are separate and kept while useful for resolving issues or remembering feedback; request their removal by email. Resend normally retains emails and delivery logs for 30 days, plus seven days in backups. Cloudflare operational logs are retained for up to seven days. Providers may retain additional security or legal records under their policies.

Your choices and updates

You can export pages, change your email, manage sessions and delete your account in Lantern. Contact angus@withlantern.app to request access, correction or deletion of other information, or to make a privacy complaint. Identity verification may be needed. Rights under applicable law remain available.

Updates will be dated here. Material changes will be notified in Lantern or by email before taking effect where practical. Optional product measurement will be explained before it is enabled.

These terms govern your use of Lantern, operated by Angus in Victoria, Australia. By creating an account or using Lantern, you agree to these terms. Contact: angus@withlantern.app.

Accounts and content

Use an email address you control, keep sign-in codes private and report suspected unauthorised access. You are responsible for your use of the account and for having permission to upload your content.

You retain your rights in your content. You grant Lantern's operator and service providers the permission needed to store, process, display to you, synchronise, back up and export it to provide and maintain the service. This does not permit publishing your private campaigns or using them in advertising. The privacy notice explains data handling and deletion.

Third-party material remains subject to its stated licences and attribution. Lantern is not affiliated with or endorsed by Wizards of the Coast.

Acceptable use

Do not use Lantern for unlawful activity, infringe others' rights, send spam or harassment, upload malicious material, access another account's content, or deliberately disrupt the service. Report security problems privately without accessing other people's information.

Access may be restricted to address abuse, security problems or breaches of these terms. Where practical and safe, you will receive an explanation and an opportunity to respond or export your work.

Service availability

Lantern is currently free. Features may change or be withdrawn. Availability, uninterrupted saving, recovery and support response times are not guaranteed. Keep exports of important work. If the service closes, reasonable efforts will be made to provide notice and an opportunity to export.

To the extent permitted by law, Lantern is provided as available without guarantees that it will be error-free or meet particular needs. Nothing in these terms excludes rights, guarantees or remedies that cannot lawfully be excluded, including under Australian Consumer Law where it applies.

Ending use and changes

You may stop using Lantern and delete your account at any time. Export anything you want to keep first. Updates to these terms will be dated here, with notice of material changes in Lantern or by email before they take effect where practical. You may stop using Lantern if you disagree with an update.
