Data storage
We often get this question from our users:
We want to start using tweak but we wondered if you have any documentation on how your app stores mock data and where it stores the data. Does it store the data on any remote servers?
We've decided to create this small page to reinforce that we do not store any of your rules/configurations/mocks data in remote servers. None of this data is ever uploaded to some server in the cloud.
Why?​
We want you to feel safe in regards of what data you use in the extension, weather these are business secrets, tokens etc. Your data is not leaving your laptop unless you export and share it.
How?​
We solely rely on the browser storage capabilities to store all your rules. Unless you press the "export" button and share your rules with someone, your data will never leave your device.
On chrome we do not use storage.sync capabilities. If you want to have your data in some other device, use import/export instead.
Usage analytics​
tweak reports anonymous product analytics to Google Analytics. Neither report ever carries the urls you intercept, your rules or their payloads, and you can turn each of them off in more options (â‹®) > Settings > Privacy.

| Switch | What it sends |
|---|---|
| Report errors | A report when something inside the extension breaks |
| Share usage data | Anonymous data about which features get used |
Both are on by default, both are remembered, and neither is reset when you clear your extension data.
Why the Firefox build has none of this​
The Firefox build ships without analytics at all, so the Privacy section says so rather than offering switches with nothing to send. That follows Mozilla's add-on guidance, which is strict about third party analytics, and we are not asking to be an exception to it.
It does have a cost, and it is worth being honest about it: we are flying blind there. We cannot see which features get used on Firefox, and we cannot see what is breaking either. A crash that error reporting would surface in a day can sit unnoticed on a Firefox build for months, simply because nothing tells us it happened.
So on Firefox, telling us is the whole channel. A bug report or a note about what you wish worked better is the only way something reaches us there, and we read every one of them.
How about my email?​
We use other platforms for identity purposes (e.g. GitHub, Google) so we do not store your email either. We
simply forward your email to our reseller. Reach out to [email protected] to follow up if any concerns.
