Translation German → English: a family hotel's guest information

Before → after (excerpt)

Original (German):

Frühstück Unser Frühstücksbuffet steht Ihnen täglich von 7:30 bis 10:00 Uhr in der Zirbenstube zur Verfügung. Wir verwenden überwiegend Produkte von Höfen aus der Region. Bei Unverträglichkeiten sprechen Sie uns bitte am Vorabend an.

Sauna Der Wellnessbereich ist von 15:00 bis 20:00 Uhr geöffnet. Bitte beachten Sie, dass in der Sauna aus hygienischen Gründen keine Badebekleidung getragen wird. Bademäntel und Saunatücher liegen in Ihrem Zimmer bereit.

Abreise Bitte geben Sie Ihr Zimmer am Abreisetag bis 10:30 Uhr frei. Eine späte Abreise bis 14:00 Uhr ist nach Verfügbarkeit gegen einen Aufpreis von 25 € möglich.

Translation (English):

Breakfast Our breakfast buffet is served every day from 7:30 to 10:00 am in the Stone Pine Room. Most of what you'll find on it comes from farms in the local area. If you have any food intolerances, just let us know the evening before.

Sauna The spa area is open from 3:00 to 8:00 pm. Please note that, as is customary in Germany, swimwear is not worn in the sauna for reasons of hygiene. You'll find bathrobes and sauna towels ready in your room.

Check-out Please vacate your room by 10:30 am on the day of departure. Late check-out until 2:00 pm is available for an extra €25, subject to availability.

Translator's notes

  • Zirbenstube — kept as a room name, translated as "Stone Pine Room" so guests can find it on signs that also show the English name
  • Sauna rule — added "as is customary in Germany": without it, many English-speaking guests read the rule as unusual or a mistake
  • Times — switched to 12-hour format with am/pm for the target audience; euro prices left unchanged

About this service

We translate the interface strings of your app or software while keeping the file structure intact: keys stay untouched, and placeholders such as %s, %d, {name} and HTML tags stay exactly where they belong. Plural forms are handled for languages that need more than two, like Russian, Polish or Arabic. Short UI strings such as buttons and tabs are kept within length so they fit the screen.

What is included

  • What you getThe translated strings in the same format you sent (JSON, XML, PO, .strings or YAML) with keys and placeholders unchanged, plus a glossary and notes on strings that may be too long.
  • Keys and placeholders untouched%s, {name}, tags and escapes kept

What we need from you

The string file content pasted into the brief, the target language, screenshots for context where meaning is unclear and any length limits.

We will ask you:

  • Which file format are the strings in?
  • Which language are we translating into?
  • Should the app address users formally or informally?
  • Are there strings with strict length limits?

Questions and answers

Can I upload the JSON or XML file?

Paste the file content into the brief as text. You get it back in the same format, ready to save.

Will the translation break my build?

We keep keys, placeholders and escapes as they were and check them, but run your usual checks before release.

Some strings are unclear without context. What then?

Add screenshots or a comment next to the key. Where it is still ambiguous, we note our choice.
