Food Data Sources and Licenses

1. Scope of this notice

Strenqo combines multiple food-data sources to help users search foods, scan barcodes, review product photos, and log meals. This page is about data attribution, source transparency, and license notices. It should be read together with the Privacy Policy and Terms of Service.

Food data is provided for fitness, wellness, and informational tracking. It is not medical advice, a clinical nutrition assessment, or a guarantee that a food label, ingredient list, allergen statement, or regulatory declaration is complete or current.

2. How Strenqo uses food data

• Text search for common foods, branded packaged foods, and regional food names.
• Barcode and QR/GS1 lookup for packaged products.
• Country-aware ranking, with priority for the user's selected market where available.
• Fallback lookup across supported markets where a product appears to be foreign or not present in the local dataset.
• Product photo display where source images are available and permitted by the relevant source terms.
• AI-assisted food photo estimates when the user chooses to upload or capture an image for estimation.
• User-created custom foods, manual corrections, and personal meal logs.

3. Open Food Facts

Strenqo uses Open Food Facts for packaged-food names, brands, barcodes, countries, nutrition values, ingredients, and product images where available. Open Food Facts is a community-built project independent from Strenqo.

Attribution notice: product information may contain data from Open Food Facts, made available under the Open Database License. Product images may be provided by Open Food Facts contributors under Creative Commons Attribution-ShareAlike terms.

Open Food Facts does not sponsor, endorse, approve, or control Strenqo. Strenqo may cache, filter, normalize, and rank Open Food Facts records to improve search quality and to exclude incomplete nutrition records from certain app flows.

4. USDA FoodData Central

Strenqo uses USDA FoodData Central for United States food search and barcode lookup where relevant, and may cache normalized records for performance and reliability.

• Source: USDA FoodData Central
• API and data documentation: FoodData Central API Guide
• Data repository: FoodData Central on Ag Data Commons

USDA and FoodData Central are independent from Strenqo. Strenqo is responsible for any normalization, filtering, ranking, or presentation choices made inside the app.

5. Food Standards Australia New Zealand (FSANZ)

Strenqo uses FSANZ Australian Food Composition Database data for Australian generic food composition coverage, alongside Open Food Facts for packaged-product and barcode coverage where available.

• Source: Australian Food Composition Database
• Data user licence: FSANZ Data User Licence Agreement
• Legal and limitation notice: FSANZ legal information

FSANZ food composition data is subject to its own attribution, share-alike, limitation, and disclaimer terms. Strenqo does not represent that FSANZ data is error-free, current for every product formulation, or sufficient for regulatory labelling compliance.

6. UK Composition of Foods Integrated Dataset (CoFID)

Strenqo uses UK CoFID-style composition data for generic food coverage in the United Kingdom, alongside Open Food Facts for packaged products and barcodes.

• Source: UK Composition of Foods Integrated Dataset
• General public-sector license reference: Open Government Licence v3.0

UK public-sector data and Crown copyright notices apply where indicated by the source. Strenqo's use of UK composition data does not imply UK government endorsement.

7. ANSES-CIQUAL

Strenqo uses ANSES-CIQUAL food composition data for French generic food coverage, alongside Open Food Facts for packaged foods and barcodes.

• Source: ANSES-CIQUAL nutritional composition table
• Online table: CIQUAL

ANSES and CIQUAL are independent from Strenqo. Strenqo may transform nutrient fields into its own per-100g display format and may filter records that do not include required macro-nutrient values.

8. BEDCA / AESAN

Strenqo uses BEDCA data for Spanish generic food composition coverage, alongside Open Food Facts for packaged products and barcode lookup.

• Source: AESAN food composition database information
• Database: BEDCA

BEDCA and AESAN are independent from Strenqo. Strenqo may normalize, translate, rank, and filter fields for app display and logging.

9. Bundeslebensmittelschlussel (BLS) / Max Rubner-Institut

Strenqo uses BLS/MRI-style composition data for German generic food coverage where available, alongside Open Food Facts for packaged-food and barcode coverage.

• Source: German Nutrient Database (BLS)
• License page: BLS license information

BLS and the Max Rubner-Institut are independent from Strenqo. Any Strenqo normalization or filtering is Strenqo's responsibility and does not imply source endorsement.

10. NEVO / RIVM

Strenqo uses NEVO/RIVM-style food composition data for Dutch generic food coverage where available, alongside Open Food Facts for packaged products and barcodes.

• Source: Dutch Food Composition Database (NEVO)
• Questions and limitations: NEVO questions

NEVO and RIVM are independent from Strenqo. Food composition values may change over time and may not represent every product formulation or preparation method.

11. PortFIR / INSA

Strenqo uses PortFIR/INSA-style food composition data for Portuguese generic food coverage where available, alongside Open Food Facts for packaged products and barcodes.

• Source: PortFIR
• Institution: Instituto Nacional de Saude Doutor Ricardo Jorge (INSA)

PortFIR and INSA are independent from Strenqo. Strenqo may transform fields into app-specific serving and per-100g formats.

12. Other regional packaged-food coverage

For Austria, Belgium, Canada, Switzerland, Ireland, the Netherlands, Portugal, the United Kingdom, Australia, France, Germany, Spain, Italy, and the United States, Strenqo may use regional Open Food Facts records and cached regional bootstrap datasets for packaged foods, barcodes, product names, brands, product photos, ingredients, and nutrition facts.

13. Internal, manual, and user-created records

Strenqo may include internal records, user-created custom foods, manual corrections, and usage signals such as confirmed selections or scans. User-created foods belong to the user who enters them, subject to the rights needed for Strenqo to store and display them inside the service.

Manual corrections may be used to improve a user's own experience or the Strenqo database where permitted by law, platform rules, and source-license obligations.

14. AI food photo and text estimates

AI food photo and text features estimate foods, quantities, and macro-nutrients from user-provided inputs. AI estimates are not taken from Open Food Facts, USDA, FSANZ, or another third-party database unless the app explicitly performs a separate lookup. AI estimates may be inaccurate and should be treated as approximate.

For ordinary text search and barcode lookup, Strenqo aims to return real database/provider matches only. If no reliable match is found, Strenqo may return no result instead of inventing a product.

15. Product photos and packaging images

Product photos shown in food search or barcode results may come from Open Food Facts contributors or other source records where images are available. Product photos may contain packaging, labels, logos, trademarks, copyrighted artwork, regulatory declarations, or other third-party rights. Display of a product image in Strenqo is for identification and food-logging support only.

Photos uploaded by users for AI food estimation are handled under the Privacy Policy and are processed to provide the requested analysis. User-uploaded photos are separate from Open Food Facts product images unless a user separately contributes them to another service under that service's terms.

16. Data quality, completeness, and freshness

• Food composition values may represent averages, label values, calculated values, imputed values, or values collected at a particular time.
• Branded products may change formulation, portion size, packaging, ingredients, allergens, or nutrition labels without Strenqo immediately knowing.
• Barcode matches can vary by country, package size, retailer, product reformulation, or reused/changed identifiers.
• Generic food composition databases may not represent a specific brand, recipe, preparation method, or batch.
• Open Food Facts is community maintained; records may be incomplete, user-contributed, or updated after Strenqo cached a copy.
• Strenqo may filter out records missing calories, carbohydrates, protein, or fat where the app requires complete macro values.

17. Attribution in the app

Strenqo may show a source label such as "Open Food Facts", "FoodData Central", "FSANZ AFCD", "ANSES CIQUAL", "BEDCA AESAN", "BLS MRI", "UK CoFID", "NEVO", "PortFIR INSA", "Internal cache", or "AI photo estimate" in search results, barcode results, or product details.

Where a record is derived from a third-party source, that source remains credited even if Strenqo caches, filters, normalizes, ranks, or formats the record for app display.

18. No endorsement

Mention of Open Food Facts, USDA, FSANZ, UK government data, ANSES, AESAN, MRI, RIVM, INSA, or any other third party does not imply that the third party sponsors, endorses, approves, audits, or is responsible for Strenqo.

19. Corrections and takedown requests

If you believe a food record, product image, source attribution, or license notice is inaccurate, contact strenqo-support@strenqo.eu. Please include the product name, barcode if available, source shown in the app, and a short description of the issue.
