How Grambo Protects Your Privacy
Fully Offline Processing
In offline mode, Grambo uses local AI models stored on your Mac. No network request is made when you correct grammar. Nothing leaves your device.
No Data Collection
Grambo does not collect, store, or analyze the text you write. There is no telemetry on your content. What you write stays on your Mac.
Optional Cloud Mode
Grambo optionally supports cloud AI models (like OpenAI or Gemini) for enhanced results. When using cloud mode, text is sent to the chosen provider — but this is always opt-in, and Grambo itself never stores your data.
macOS Sandboxing
Grambo runs within macOS security boundaries. It does not access your files, contacts, or system data beyond what is required to process selected text.
Privacy-First Design
Privacy is not a feature added later. It is the foundational design principle of Grambo. The default mode requires no internet and transmits no data.
Grambo vs Cloud-Based Grammar Tools
Most grammar tools — including Grammarly and LanguageTool — send your text to remote servers for processing. This means your writing, including sensitive emails, legal documents, and private notes, passes through systems you do not control.
Grambo is different. By default, all processing happens on your Mac using local AI models. You do not need to trust an external server with your writing.
This makes Grambo the right choice for users in privacy-sensitive roles: lawyers, medical professionals, journalists, developers working on proprietary code, and anyone who values data sovereignty.
Frequently Asked Questions
Does Grambo work offline?

Is Grambo a Grammarly alternative?
Yes, Grambo is a privacy-focused alternative to Grammarly that runs locally on macOS. It does not send your text to the cloud.
Does Grambo send data to the cloud?
No. Grambo processes all text locally on your device and does not send it to external servers by default.
Does Grambo store my writing?
No. Grambo does not store your writing. Text is processed in-memory during correction and is not saved or transmitted anywhere.
Can Grambo be used for sensitive or confidential writing?
Yes. Because Grambo processes text locally, it is safe to use for confidential documents, legal writing, medical notes, and proprietary code.
What happens if I use cloud AI mode?
If you choose to use a cloud AI model (such as OpenAI), your text is sent to that provider under their privacy policy. Grambo itself never stores this data. The default offline mode sends nothing externally.
