Innerholm vs Diarium: a private journal you can open in any browser
Diarium is a well-loved journal app, especially on Windows, where it won a Microsoft Store Award. It keeps your data on your own devices and cloud. Innerholm trades that for sync that just works and a journal you can open in any browser. Here is an honest comparison.
Diarium and Innerholm are both private journals, but they make opposite trade-offs. Diarium is a one-time purchase per platform with native apps and bring-your-own-cloud sync, so your data never touches the developer's servers, but you set up and maintain the cloud link yourself. Innerholm is web-first with built-in sync and nothing to configure, stores entries on its own servers, and commits explicitly to no content scanning and no AI training. Choose Diarium for a one-time price, rich media, and data that stays on your side; choose Innerholm for zero-setup sync, browser access on any device, and a Diarium importer.

- Want an explicit no-scanning, no-AI-training commitment in writing
- Are coming from Diarium and want to bring your entries across
- Like that AI is there if you ask for it, and silent until you do
Choose Diarium if you...
- Want a one-time purchase and no subscription, ever
- Prefer your data to live only on your own devices and cloud
- Write on Windows and want a native, award-winning app
- Attach audio, video, and arbitrary files to entries
- Like automatic context: weather, fitness, calendar, location, maps
- Need solid offline writing without a connection
Moving from Diarium to Innerholm
If you mostly write on one Windows machine and never need the web, Diarium is hard to beat. People tend to look for an alternative when the per-platform purchases add up, when the bring-your-own-cloud sync gets fiddly across devices, or when they want to open their journal on a borrowed laptop without installing anything.
Innerholm has a Diarium import path so you do not start over. Export your Diarium journal, then bring your entries, dates, and tags into Innerholm. The step-by-step guide lives here:
Privacy: two honest models
This is the most interesting difference, and it is not a case of one app being private and the other not.
Diarium keeps your entries on your device and syncs them through a cloud account you own. The developer never stores or reads your writing. That is a genuinely strong privacy position. The cost is that the sync link is yours to set up and keep working, and your privacy is only as good as the cloud account you point it at.
Innerholm stores entries on its own servers so that sync and search work without any setup and your journal is reachable from any browser. In exchange it commits explicitly to no content scanning for any purpose, no AI training on your journal text, no behavioural profiling, and no advertising. Every data-touching feature is off by default and asks before it turns on.
Neither app should hold legally sensitive content without advice from a lawyer. For most people the choice is simple: Diarium if you want data on your side and do not mind the setup, Innerholm if you want it to just work with an explicit promise about what is never done with your words.
Frequently asked questions
Is Innerholm a good Diarium alternative?
Yes, if you want sync without setup and access from any device through the browser. Diarium is bought per platform and its sync depends on a cloud account you configure yourself. Innerholm has built-in sync, runs on the web, is free during early access, and can import a Diarium export. Diarium is the better fit for a one-time price, rich media, and data that stays on your own devices and cloud.
How much does Diarium cost?
Diarium is a one-time purchase, roughly $5 to $10 per platform, with no subscription. It is free on most platforms with an optional Pro unlock, and on Windows it is a paid app that already includes Pro. Innerholm is free during early access, with a paid Innerholm+ tier planned but not yet priced.
Does Diarium sync across devices?
Yes, through your own cloud. Diarium syncs across Windows, Android, iOS, and macOS using a storage account you connect, such as OneDrive, Google Drive, Dropbox, iCloud, or WebDAV. It keeps your data out of the developer's hands, but the link is yours to maintain. Innerholm syncs through your Innerholm account with nothing to configure.
Can I import my Diarium journal into Innerholm?
Yes. Export your Diarium journal and follow the Innerholm import guide to bring your entries, dates, and tags across. The current steps are at innerholm.com/import/from-diarium.
Does Innerholm work offline like Diarium?
Not as fully. Diarium's native apps write locally first and sync when connected, so offline writing is solid. Innerholm is web-based and currently needs a connection to sync. Offline-first support is on the longer-term roadmap.
