Google Translate vs DeepL Pro vs SimplyTranslate: A 2026 Privacy Showdown

Three translation tools dominate the conversation in 2026: Google Translate, the default most people end up with; DeepL Pro, the quality-first option; and SimplyTranslate, the privacy-first frontend. They make different trade-offs on accuracy, privacy, cost, and convenience, and those trade-offs are not subtle.

This guide is for anyone comparing them for regular use. It sets them against each other on privacy practices, translation quality, feature set, and day-to-day usability, so the choice is based on what each service actually does rather than on vague reputation.

Key takeaways: Google has the widest language support but the weakest privacy. DeepL Pro gives the best quality for European languages with reasonable privacy. SimplyTranslate gives you Google or DeepL quality with meaningful privacy protection at no cost.

Privacy, side by side

Google Translate

Google collects a lot here: text, IP address, device information, account data, and usage patterns. The text may be retained and used for model training, the service is tied to your Google profile, and the data does not sit in a neat little silo - it moves across Google's wider ecosystem. Privacy grade: poor.

DeepL Pro

DeepL Pro keeps collection down for paying subscribers, and Pro text is not retained for model training. You still need an account, but data sharing is limited, and the service is built around GDPR compliance with EU data processing. Privacy grade: good for Pro, moderate on the free tier.

SimplyTranslate

The frontend itself does not collect data, and it does not store text. There is no account requirement. The catch, as always, is the instance operator. Privacy grade: strong.

SimplyTranslate is available through public instances, including Tor and I2P endpoints for maximum anonymity.

Which engine handles which language best

Translation quality changes by language pair. That is the part people like to flatten into a single winner, which is rarely accurate.

European languages (EN-de, EN-fr, EN-es, EN-it)

DeepL Pro is the clear leader here. Its translations are usually the most natural-sounding. Google Translate is very good and reliable. SimplyTranslate using a Google backend is identical to Google Translate, while SimplyTranslate using a DeepL backend comes close to DeepL quality.

Asian languages (EN-zh, EN-ja, EN-ko)

Google Translate tends to be stronger for these pairs. DeepL Pro is good and still improving, but it remains behind Google for some combinations. SimplyTranslate with a Google backend matches Google here as well.

Less common languages

Google Translate covers 130+ languages, but quality falls off with rarer pairs. DeepL Pro is much more limited and does not support many less common languages. SimplyTranslate depends entirely on the backend you pick.

Feature differences that matter in practice

Feature	Google Translate	DeepL Pro	SimplyTranslate
Languages	130+	~30	Backend-dependent
Document translation	Yes	Yes (excellent)	Text only
API access	Paid	Paid	Free
Offline mode	No	No	No
Formality control	No	Yes	Via DeepL backend
Glossary support	No	Yes (Pro)	No
No account required	Partial	No	Yes
Cost	Free	$9-500/mo	Free
Tor/I2P access	No	No	Yes
Self-hostable	No	No	Yes

Where Google Translate still makes sense

Google Translate still has legitimate use cases, even with its privacy problems. It is fine for translating non-sensitive public content where privacy is not a concern. It also covers languages DeepL and other services do not support. And if the job is a one-off translation, convenience often wins, whether or not that is the elegant answer.

Even then, using Google Translate through SimplyTranslate keeps the same translation output while removing direct tracking. That is the practical upgrade covered in our translating without Google guide.

Where DeepL Pro earns its subscription

DeepL Pro is worth paying for when translation quality is the priority, especially for European languages. It also makes sense if document translation is part of the workflow, because PDF, Word, and PowerPoint support is built in.

The other strong reason is consistency. Glossaries and formality controls matter when branded terms need to stay put and tone needs to stay uniform. If an organisation needs a data processing agreement for compliance, that is another point in DeepL Pro's favour. And yes, budget still matters. If there is no budget for a paid service, that settles the question quickly.

Our earlier privacy-first translators review covers DeepL's privacy posture in more detail.

Where SimplyTranslate fits best

SimplyTranslate is the strongest fit when you want the best available translation quality without direct tracking. It also makes sense if you cannot or will not pay for a translation service, need Tor or I2P access for anonymous translation, want to self-host the interface for personal or team use, or prefer a lightweight setup with JavaScript optional.

For team deployments, our private translation APIs guide covers self-hosting for organisations.

The practical decision

For most privacy-conscious users, the working answer is straightforward:

1. Default: SimplyTranslate through a trusted instance - Google-quality accuracy with privacy protection, at zero cost
2. Professional needs: DeepL Pro - when translation quality is critical for business and the budget is available
3. Direct Google: Only for languages not covered by DeepL, accessed via the SimplyTranslate frontend
4. Sensitive content: On-device translation or local LLMs for text that should never leave your device

Privacy and trust are not the same thing

The privacy comparison is not as simple as saying SimplyTranslate wins and calling it done.

SimplyTranslate instance trust still matters, because the operator can see your text. Choose carefully. DeepL Pro's legal protections are different again: contractual data processing agreements create legal accountability, which is not the same as total secrecy but is not nothing either. Google through SimplyTranslate still processes the text, it just cannot link the request to your identity. Self-hosting removes the instance-trust question entirely.

FAQ and takeaways

If SimplyTranslate uses Google's engine, is it really more private? Yes. Google cannot link the translation to your identity. The difference is between Google knowing "user X translated this sensitive text" and "an anonymous request translated this text."

Is DeepL Pro worth the money? For professional translation of European languages, yes. For casual use, SimplyTranslate gives comparable quality at no cost.

Can I switch backends in SimplyTranslate? Yes. Most instances let you choose between Google, DeepL, LibreTranslate, and other engines.

Which is fastest? Google and DeepL respond near-instantly. SimplyTranslate adds a little latency because it proxies the request, but for a single translation it is usually not noticeable.

Bottom line: SimplyTranslate gives you the best privacy-quality ratio for free. DeepL Pro earns its cost for professional work. Direct Google Translate is rarely necessary when SimplyTranslate offers the same quality with better privacy. Choose the most private option that still does the job.
