Terms of Service

Last Updated: September 14, 2026

These are the terms on which we sell and supply Meru. We have kept them short and in plain English. They give you rights as well as setting out ours, and nothing in them takes away the rights the law gives you. If anything here is unclear, email us before you buy and we will explain it.

1. Who we are and how to contact us

Meru is made by Zoid Ltd (“Zoid”, “we”, “us”), registered in England and Wales, company number 14931728, with a registered office at 167-169 Great Portland Street, 5th Floor, London, England, W1W 5PF.

Email tim@meru.so. These terms are an agreement between you and Zoid, and they cover the Meru app, the website at meru.so and the customer portal at portal.meru.so.

2. What Meru is

Meru is a desktop client for Gmail for macOS, Windows and Linux. It puts Gmail in a native window with the features described on our website.

Meru shows Gmail in a browser session on your own device, so your mail stays between you and Google. Your use of Gmail is governed by your own agreement with Google.

Meru is not affiliated with or endorsed by Google. Gmail and Google are trademarks of Google LLC. Google can change, restrict or withdraw Gmail whenever it likes, and a change on Google’s side can stop a Meru feature working. We will do what we reasonably can to adapt, but Gmail is not ours to control.

3. Open source and Meru Pro

Meru’s source code is public at github.com/zoidsh/meru under the GNU Affero General Public License version 3. You are free to use, study, change and share it on the terms of that license, whatever else these terms say.

Meru Pro is a separate thing: a paid license that unlocks the Pro features in the official builds we distribute, which check with our servers that the license is valid. What you buy is that license and the service behind it, not the code, which is public either way.

The AGPL text includes a disclaimer of warranty aimed at the code as code. It does not reduce the rights you have against us under these terms or under the law when you buy Meru Pro from us.

4. Free, trial and Pro

Free. Meru is free to use with your first Gmail account and the feature set described on our website. It costs nothing and needs no account.

Trial. Every install starts a 14-day Meru Pro trial on first launch, automatically, with nothing to sign up for. The trial is one per device, and the app identifies the device by a one-way hash as described in our privacy policy. When the trial ends, Meru keeps working as the free version.

Pro. Meru Pro is a one-time payment at the price shown on our website when you buy. A Pro license covers 3 devices, and you can buy extra device slots up to a total of 5.

We may offer other plans in future, such as subscriptions or plans for teams. If we do, their terms, price and billing period will be shown to you before you buy.

5. Buying Meru Pro

Purchases go through Stripe Checkout using Stripe Managed Payments, which may appear as “Link” or “Onelink” on the payment page and on your statement.

Stripe is the merchant of record for your purchase. That means Stripe, not us, is the seller for the payment, and Stripe:

  • collects the payment, so we never see or hold your card details
  • works out, collects and remits VAT, sales tax or GST in the countries where it supports this
  • may convert the price into your local currency
  • sends your receipt and invoice
  • handles payment disputes and questions about the payment itself
  • may issue a refund directly, within 60 days of the purchase

The price you see at checkout is the price you pay, with tax included where Stripe collects it. Stripe’s own purchase terms apply to the payment alongside these terms.

What reaches us is your email address, a purchase reference, the amount and the tax location. We then email your license key. Your agreement for the software license itself is with us, and these terms govern it.

You must be at least 18 to buy Meru Pro.

6. Cancelling and refunds

Our money-back guarantee. If you are not happy with Meru Pro, tell us within 14 days of your purchase and we will refund you in full. You do not need a reason, and there are no conditions. Email tim@meru.so from or about the address you used to buy.

Your statutory right to cancel. As a consumer buying at a distance you normally have 14 days to change your mind about digital content. If you ask for the download or access immediately and agree to it, you can lose that right once the download starts. Our guarantee covers the same 14 days either way, so you get the refund regardless of which one applies.

We refund to the original payment method, within 14 days of agreeing the refund and usually sooner. Because Stripe is the merchant of record it may handle the refund directly, so it will show on your statement as coming from Stripe or Link. When a purchase is refunded, we disable the license key and deactivate its devices. You can carry on using the free version, and the source code stays available to you under the AGPL.

7. Using Meru fairly

We ask you not to:

  • share, resell, rent or publish your license key, or use a key you did not buy
  • work around the device limit, the license checks or the trial limit, including by faking device identifiers or starting repeated trials on one device
  • use Meru to break the law, to send spam or malware, or in breach of your agreement with Google
  • present Meru as your own product, or as affiliated with or endorsed by Google
  • attack our servers, or try to reach accounts or data that are not yours

None of this limits what the AGPL lets you do with the source code. It is about the Pro license and our servers.

8. License keys and devices

A Pro license activates on up to 3 devices, or up to 5 if you buy extra slots. You can rename a device in the app’s settings and remove one in the portal at portal.meru.so, and removing a device frees its slot for another.

We may suspend or disable a license key if we have good reason to believe it is being used fraudulently, if the payment is reversed by a chargeback, or if these terms are broken seriously or repeatedly. Except where we believe fraud is in progress, we will email you first, tell you why, and give you a fair chance to respond or put it right. If we get it wrong, we will restore your license. Disabling a Pro key does not stop you using the free version or the source code.

Nothing in these terms affects the rights the law gives you, and we do not ask you to give any of them up.

If you are a consumer, the Consumer Rights Act 2015 says that digital content we supply must be as described, fit for its purpose, and of satisfactory quality. If it is not, you are entitled to have it repaired or replaced, and to a price reduction or a refund where that cannot be done or is not done within a reasonable time.

If our digital content damages your device or other digital content belonging to you, and this happened because we failed to use reasonable care and skill, we will either repair the damage or pay you compensation.

10. Our responsibility to you

We do not exclude or limit our liability in any way where the law does not allow it. That includes liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, and for your statutory rights as a consumer.

We are responsible for loss or damage you suffer that is a foreseeable result of our breaking these terms or failing to use reasonable care and skill. Loss is foreseeable if it is obvious that it will happen, or if, when you bought, we both knew it might.

We are not responsible for:

  • losses that were not foreseeable
  • business losses, since Meru is supplied to consumers for private use; if you use it for business, section 11 applies
  • Google changing, restricting or withdrawing Gmail, or a Gmail change breaking a feature, since that is outside our control

For consumers, our total liability for any other loss is limited to the amount you paid for your license. That limit does not apply to anything in the first paragraph of this section, or anywhere else the law says it cannot.

11. Business customers

If you buy or use Meru for a business purpose, these terms apply to you with three differences. Rights that the law gives to consumers only do not apply to you. Our total liability to you in any 12-month period is limited to what you paid us in the previous 12 months. And we are not liable to you for loss of profit, revenue, business, goodwill or data.

Nothing in this section limits liability that cannot be limited by law, including anything in the first paragraph of section 10.

12. If we discontinue Meru

If we stop offering Meru, we will make reasonable efforts to release a version that lets Pro users carry on using the features they paid for without our servers validating the license. After that there would be no updates, no security fixes and no support, and continued use would be at your own risk. The source code stays public under the AGPL.

13. Changes to these terms

We may change these terms, and only for one of these reasons: a change in the law or in regulation, a change to Meru’s features or to how we price and sell it, security, or making something clearer without changing what it means.

For a material change we will give you at least 30 days’ notice, by email to the address on your license or portal account, or in the app. If a material change affects a paid product and you do not accept it, you may end the agreement and we will refund, pro rata, any paid period you have not used.

If you bought a one-time Meru Pro license, a change to these terms will not take away anything you paid for.

14. Governing law

These terms are governed by the law of England and Wales, and the courts of England and Wales have non-exclusive jurisdiction over any dispute.

If you are a consumer living elsewhere, you keep the protection of any mandatory law of the country you live in, and you can bring a claim in your local courts. We do not require arbitration and we do not ask you to give up your right to go to court.
