Contractor‑Ready Localization Kit for Playables and Store Assets

Return to blogCONTRACTOR‑READY LOCALIZATION KIT FOR PLAYABLES AND STORE ASSETS
Localization projects stall when contractors receive incomplete briefs: wrong screenshot sizes, missing acceptance tests, unclear privacy text, or metadata that trips store review. This post gives you a compact, battle-tested 6‑file kit — copy + screenshots + JSON‑LD + locale QA checklist + acceptance tests + privacy microcopy — that founders can hand to any contractor so they can localize playables and store listings without breaking review or SEO.
Section 1
What your 6‑file Contractor‑Ready Kit contains (and why each file matters)
Packaging your localization request as six discrete, purpose-built files reduces ambiguity and review risk. Each file maps directly to a stage in the contractor’s workflow and to a store requirement reviewers might check.
Keep each file small, unambiguous, and consumable by non‑product-native contractors. The contractor should be able to open the folder and start localizing immediately — no back‑and‑forth about formats or missing specs.
- 1. Copy file (CSV or XLIFF): source strings + context keys + length limits
- 2. Screenshot package: layered PSD/FIG or high‑res PNGs + caption placeholders and target sizes
- 3. JSON‑LD metadata: structured SoftwareApplication snippet for web demo pages and marketing pages
- 4. Locale QA checklist: language, punctuation, direction, imagery appropriateness, in‑context screenshot check
- 5. Acceptance tests: store submission smoke tests and reviewer edge‑cases
- 6. Privacy microcopy: short, locale‑aware lines for permission prompts and short privacy blurbs
Section 2
File 1 — Copy: structure, context and character limits
Deliver store copy as a single table (CSV or XLIFF) with these columns: key, source_text, context/usage, character_limit, screenshots_refs, screenshot_index. Context prevents literal, ambiguous translations and the limit enforces store field sizes (e.g., short subtitle fields).
For playables and in‑app demo captions, include example screenshots or short GIFs so translators can see where the text sits. This reduces truncation and layout regressions during upload and review.
- Include a short context line for every string (e.g., ‘CTA on onboarding card, 1 line, bold’).
- Mark strings that are user‑facing vs developer/logging text — only translate user‑facing.
- Add an explicit character_limit column tied to target store field sizes.
Section 3
File 2 — Screenshots: export targets, alt copy and reviewer-safe art
Provide screenshot masters in a design format (PSD, Figma) and export presets for each store. Include the exact pixel sizes and orientation (App Store Connect and Google Play have different required sets). This prevents contractors from producing wrong dimensions that you’d then have to rework before submission.
Flag any imagery that could trigger review concerns: real personal data, visible faces without releases, gambling-style content, or simulated purchases. Use neutral placeholder data for playables (fake accounts, masked emails) and call that out in the package.
- Export presets: list pixel sizes and filenames per store locale.
- Provide both localized caption text and a screenshot preview that overlays the translated caption so translators can check fit.
- Specify whether imagery must change culturally (date format, currency, illustrations).
Section 4
File 3 — JSON‑LD: structured metadata for your demo and SEO
Include a minimal SoftwareApplication JSON‑LD snippet (schema.org) that contractors can paste into localized demo pages or marketing landing pages. That preserves structured metadata across languages and reduces SEO friction when you publish localized demo pages.
Keep JSON‑LD language fields explicit and pair each snippet with the locale code and a short usage note (e.g., page URL, canonical link behavior). This prevents duplicate content or mis-tagged language that could hurt search discoverability.
- Deliver one JSON‑LD file per target locale with: name, description, applicationCategory, operatingSystem, url, screenshot, inLanguage.
- Add instructions to set correct hreflang and canonical pointing back to the primary language when appropriate.
- Avoid embedding sensitive keys or environment tokens in JSON‑LD.

Section 5
File 4 & 5 — Locale QA checklist + Acceptance tests
Provide a compact QA checklist that a local reviewer or contractor can run through before handing assets back. The checklist should include checks for truncation, line breaks, RTL layout, date/currency formats, text overlap on screenshots, and review‑policy flags such as real personal info in screenshots.
Acceptance tests are runnable, low‑effort checks the contractor must pass before you accept work: upload one localized screenshot to a staging listing, run a screenshot checklist, open the localized demo page with the locale JSON‑LD and check the structured data, and verify the privacy microcopy displays where specified.
- Locale QA checklist items: truncation, context accuracy, image appropriateness, RTL support, punctuation and plurals.
- Acceptance tests: staging screenshot upload, demo page JSON‑LD verification, sample device check for each orientation.
- Require contractor signoff and short screencap proof for each passed test.
FAQ
Common follow-up questions
Why include JSON‑LD for store localization? Isn’t that only for web pages?
JSON‑LD (SoftwareApplication schema) helps search engines understand your demo and marketing pages in each language. Including per‑locale JSON‑LD ensures structured metadata (name, description, screenshots, inLanguage) matches the localized page and reduces indexing errors or duplicate‑content problems.
How do I avoid store review rejections when localized screenshots show user content?
Use anonymized or placeholder account info in screenshots, obtain releases for any real faces, and flag screenshots that include potential reviewer‑sensitive content in the kit. Apple and Google explicitly review for privacy and deceptive claims; call out any simulated transactions or UGC in the package so translators know to redact sensitive details.
What format should I deliver copy for most contractors?
Deliver strings as CSV or XLIFF with columns for key, source_text, context, character_limit and screenshot_refs. XLIFF is preferred for professional translators and tooling; CSV is acceptable for contractors who prefer spreadsheet workflows.
Should I localize privacy microcopy differently from other UI copy?
Yes. Privacy microcopy is legally sensitive and may need both translation and legal review. Provide a short, localized privacy blurb for prompts and clearly separate it from marketing copy in the kit so translators know the tone and compliance requirements.
