Kurz gesagt
Die Zusammenfassung oben ist eine unverbindliche Übersetzung. Der vollständige Text unten ist auf Englisch, und maßgeblich ist die englische Fassung.
These terms are the rules for using MailAfter, in plain words. By creating an account or using the MailAfter Chrome extension you agree to them and to our Privacy Policy, which explains what we collect and why.
1. Who we are
MailAfter is operated by KLabs (“we”, “us”). Contact: support@mailafter.app.
2. The service
MailAfter tells you when emails you send from Gmail are opened. A Chrome extension adds a tiny image to the emails you send while MailAfter is switched on. When the recipient’s mail app loads that image, we record the open, and you see it in your dashboard and in the extension.
It is free while we launch. We may introduce paid plans later. We will tell you before any charge applies, and nothing is charged without your agreement.
3. Who can use it
You must be at least 16 years old (or older, if the law of your country sets a higher minimum age for this kind of service) and able to enter a binding agreement. MailAfter is not for children. If you use MailAfter for an organisation, you confirm that you may accept these terms on its behalf. You may not use MailAfter if the law forbids it in your country or if we have closed your account.
4. Your account and connection key
- Give a valid email address and keep your details accurate.
- Keep your password, recovery codes and connection key private. You can end sessions and disconnect devices in Settings.
- Tell us at support@mailafter.app if you think someone else used your account.
- You are responsible for what happens under your account.
5. What MailAfter does, and what it cannot do
MailAfter detects an open when a mail app loads the tiny image. That has limits you should know about, so that you read the results correctly:
- Missed opens. If the recipient’s mail app blocks images, or the recipient has turned image loading off, the open is not seen.
- False or inflated opens. Some privacy features, such as Apple Mail Privacy Protection, and some mail systems and security scanners load images automatically, even if nobody read the email. MailAfter labels the ones it recognises as likely automatic and keeps them out of your open count and alerts, but it cannot recognise all of them, and it may label a real open as automatic. Forwarded emails and previews can also trigger opens.
- Hidden details. Image proxies, such as Gmail’s or Apple’s, hide the real time, device and location of the reader. The time you see can be the time the proxy loaded the image.
- Your own views. The extension blocks the tracking image while you read your own sent emails, and opens within about a minute and a half of sending are labelled as likely automatic, so that your own views and instant scans do not appear as opens. You can also switch tracking off for a single email before you send it.
- Several recipients. If an email has more than one recipient, MailAfter cannot tell which of them opened it.
- No reading proof. An open does not show that the email was read, understood or agreed to, and it is not evidence for legal or disciplinary purposes.
MailAfter does not read your message text or attachments, and it does not send emails for you.
6. Acceptable use
You may use MailAfter only for lawful, legitimate purposes. You must not use it, or let anyone else use it, to:
- stalk, monitor, surveil or keep tabs on an individual, or to watch someone against their rights or wishes;
- harass, threaten, intimidate or abuse anyone;
- commit or support fraud, scams, phishing, impersonation, or any other deceptive or criminal activity;
- send spam or unsolicited bulk email;
- build profiles of people, or make decisions about them, in a way the law forbids;
- track children or anyone under 16, or anyone you know or suspect cannot lawfully be tracked;
- break any consent, ePrivacy, data-protection, anti-spam or other law that applies to you or to your recipients;
- copy, decompile, reverse-engineer or try to extract the source code of the service or the extension, except where the law expressly allows it;
- attack, overload, probe or disrupt the service or its infrastructure, bypass its limits, security or protections, or access it in ways we did not provide;
- scrape, harvest or collect data from the service by automated means, or use bots or scripts to create accounts or trackers;
- resell, sublicense or offer the service to others without our written permission; or
- use the service in breach of the export and sanctions rules in section 14.
Fair-use limits apply (for example, a daily cap on new trackers and limits on sign-ups). The examples above are not a full list: anything unlawful, or likely to harm people or the service, is not allowed.
7. Your responsibility, and telling your recipients
You alone are responsible for how you use MailAfter and for what you do with the information it shows you. In particular, you are solely responsible for making sure your use is lawful where you and your recipients are, and for giving recipients any notice, and getting any consent, that the law requires before you track them. This applies in many countries, for example under the ePrivacy rules and the GDPR in the EU and UK. We do not send that notice for you, and we cannot check whether you have done so.
8. Your data
You keep ownership of your data: the details of the emails you track and the opens recorded for them. You allow us to process it only to provide the service, as described in the Privacy Policy. We do not claim any other rights to it, and we do not sell it.
9. Reporting misuse, and requests from authorities
If you think MailAfter is being used against you or against someone else, or you want to report any breach of these terms, write to support@mailafter.app with the details. We review reports and may act on them as set out in section 11.
We cooperate with law enforcement and courts only when we receive valid legal process, and we disclose only what that process legally requires.
10. Availability and changes
We work to keep MailAfter running, but we do not promise uninterrupted or error-free service. MailAfter depends on Gmail and Chrome, which can change without notice and may affect how it works. We may change, limit or discontinue features, and we will give reasonable notice of significant changes where we can.
11. Suspension and ending your use
You can stop at any time: switch tracking off or uninstall the extension, and delete your account in Settings (you can download your data first). Deleting your account removes your data as described in the Privacy Policy. Emails you already sent keep their tiny image, but once your account is deleted nothing is recorded for them.
We may, at our discretion and without notice, limit, suspend or end your access, and remove related trackers and data, if we suspect misuse, if you break these terms or the law, if needed to protect the service, other people or the law, or if we stop offering the service. Where we reasonably can and the law requires it, we will tell you and let you download your data. Sections that by their nature should continue (including 7 and 13 to 18 and 21) stay in force after your access ends.
12. Third parties
MailAfter is independent. Gmail, Google and Chrome are trademarks of Google LLC; MailAfter is not affiliated with, endorsed or sponsored by Google. If you connect Telegram, Telegram’s own terms apply to that service.
13. No warranty
The service is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including any warranty of merchantability, fitness for a particular purpose, accuracy or non-infringement, to the extent the law allows. In particular, we do not promise that open information is complete or accurate (see section 5), that the service will be uninterrupted or secure, or that it will meet your needs.
14. Export and sanctions compliance
You confirm that you are not on any government list of restricted or sanctioned persons, that you are not in a country or region under comprehensive sanctions or an embargo that applies to us, and that you will not use or give access to MailAfter in breach of export-control or sanctions laws.
15. Limit of liability
To the extent the law allows, we are not liable for any indirect, incidental, special, consequential or punitive loss, or for lost profits, revenue, data, goodwill or business, however caused. To the extent the law allows, our total liability to you for all claims relating to MailAfter is limited to the greater of (a) the amount you paid us for the service in the 12 months before the event that gave rise to the claim, and (b) EUR 100.
Nothing in these terms limits or excludes liability that cannot be limited or excluded by law. This includes liability for death or personal injury, for fraud, for intentional wrongdoing or gross negligence, and your statutory rights as a consumer.
16. Indemnity
To the extent the law allows, you agree to defend, indemnify and hold harmless KLabs and the people who work for it from any claim, demand, loss, damage, fine, cost or expense (including reasonable legal fees) arising out of or relating to your use of MailAfter, your breach of these terms or the law, your failure to give required notice or get required consent, or your violation of anyone’s rights. We may take over the defence of any matter at your expense, and you will not settle it without our written consent.
17. Individual claims only
To the extent the law allows, you and we may each bring claims against the other only on an individual basis, and not as a plaintiff or class member in any class, collective or representative action. This does not limit rights that the law gives you and that cannot be waived, such as collective redress rights of consumers in the EU.
18. Governing law and disputes
These terms, and any dispute about them or about MailAfter, are governed by the law of the country where KLabs is established, without its conflict-of-law rules. The courts of that country have jurisdiction, except where the law gives you the right to go to another court. We will confirm the country in writing if you need it to bring or answer a legal claim. If you are a consumer, you keep the mandatory protections of the law of your country of residence and any right to bring a claim in the courts of that country.
19. Events beyond our control
We are not liable for any failure or delay in providing MailAfter caused by events beyond our reasonable control, such as outages of internet, hosting, Google, Chrome or Telegram services, power or network failures, cyber-attacks, natural disasters, war, terrorism, strikes, epidemics, or acts of government. We will resume the service as soon as we reasonably can.
20. Changes to these terms
If we change these terms in a meaningful way we will update the date above and, where appropriate, tell you in the product before the change applies. If you do not agree to a change, you can delete your account. If you keep using MailAfter after the change applies, you accept it.
21. General
- Entire agreement. These terms and the Privacy Policy are the whole agreement between you and us about MailAfter and replace any earlier understanding.
- Severability. If a part of these terms is found invalid or unenforceable, that part is limited or removed as far as necessary and the rest stays in force.
- No waiver. If we do not enforce a right right away, we have not given it up.
- Assignment. You may not transfer your account or these terms to anyone else without our written consent. We may transfer them to another business that takes over MailAfter, and we will tell you if we do.
- Notices. We may send you notices by email to your account address or through the product. You can write to us at support@mailafter.app.
- Consumers in the EU. If you are a consumer, nothing in these terms takes away the mandatory rights you have under the consumer-protection law of your country of residence. Where these terms conflict with those rights, those rights apply.
- Language. Translations of these pages are for convenience; the English version governs.
22. Quick answers
Is MailAfter free?
Yes, while we launch. If we introduce paid plans we will tell you first, and nothing is charged without your agreement.
Can I rely on an “Opened” for something important?
Treat it as a strong hint, not proof. Some mail apps load images without anyone reading, and others block them. See section 5.
Do I have to tell my recipients?
Where the law requires it, yes. In many places, including the EU and UK, tracking people can require notice or consent. That duty is yours.
Can I leave and take my data?
Yes, any time. Download your data in Settings, then delete your account. Everything is removed as described in the Privacy Policy.
How old do I have to be?
At least 16, or older if your country requires it.
Can I use it to monitor a person?
No. Stalking, surveillance, harassment, spam, phishing, fraud and any unlawful tracking are forbidden, and we can suspend accounts without notice for suspected misuse. See section 6.
How do I report misuse?
Write to support@mailafter.app with the details. We review every report.
Is MailAfter connected to Google?
No. MailAfter is an independent product. It works with Gmail through your browser but is not made, endorsed or supported by Google.
